Cuadrado Magico Grado 11 (PG1118) En un pueblo hay un mago que sorprende a los niños dibujando en la arena cuadrados mágicos que tienen un número impar de filas y columnas y donde la suma de cada fila columna y diagonal es la misma e igual al número mágico M = n(n^2+1)/2. Lo que los sorprende aun más es que el cuadrado contiene los números naturales consecutivos empezando desde 1 hasta n^2. Por ejemplo, los cuadrados que ha dibujado el mago de orden 3, 5 y 7 se muestran a continuación. Cuadrado mágico de orden 3   2   7   6   9   5   1   4   3   8 M=  3*(3^2+1)/2 = 15   Cuadrado mágico de orden 5   9   3  22  16  15   2  21  20  14   8  25  19  13   7   1  18  12   6   5  24  11  10   4  23  17 M= 5*(5^2+1)/2 = 65   Cuadrado mágico de orden 7 20  12   4  45  37  29  28  11   3  44  36  35  27  19   2  43  42  34  26  18  10  49  41  33  25  17   9   1  40  32  24  16   8   7  48  31  23  15  14   6  47  39  22  21  13   5  46  38  30 M= 7*(7^2+1)/2 = 175   Lo que no saben los niños es que el mago utiliza el siguiente algoritmo para dibujar el cuadrado mágico. Coloca el número 1 en la mitad de la última columna y cada nuevo consecutivo lo coloca en la casilla de la matriz que esta arriba y a la derecha de la casilla de la casilla actual. La matriz se considera “circular”; es decir, la columna a la derecha de la última se considera la primera (la columna más a la izquierda) y la fila encima de la primera se considera la última (la fila más abajo).  Si durante el proceso de llenado de la matriz, una entrada ha sido ocupada, el consecutivo se coloca a la izquierda de la casilla actual. Con este método el mago puede dibujar cuadrados mágicos de orden —número de filas y columnas— impar pero no par. Elabore un programa que lea una línea  así: Input de entrada con un número natural n impar Output y que produzca como salida varias líneas donde la primera contiene el número mágico M = n(n^2+1)/2 y las subsiguientes las filas del cuadrado mágico. Los números del cuadrado mágico se separan con un espacio. Example Input: 3 Output: 15 2   7   6 9   5   1 4   3   8   Input: 5 Output: 65 9   3  22  16  15 2  21  20  14   8 25  19  13   7   1 18  12   6   5  24 11  10   4  23  17

Mozahid the forgetful (MOZMTF) Mozahid is a forgetful programmer. He is so forgetful that sometimes he forget at night the problem he solved that morning :( One morning he collect a number which consist of 11 digits and do not have any leading zeroes (Example 12345678910 is correct but 01234567891 is not). He was trying to collect it from the previous year and after a long one year try he managed to collect it and it is sure that probability to find it again is near to 0%. At the night he found that instead of writing 11 digits of the number he wrote 10 digits and unfortunately missed 1 digit. But he was sure that all the 10 digits are correct and the relative order of the digits in the number was not changed. As he is forgetful, he forgot what was the number . But this time fortunately he know the total sum of all 11 digits of the original number and he is also sure that the number was maximum among all possible way of restoring the number. As Mozahid is frustrated about why he can’t easily remember anything, he is not interested to restore the number at the moment. Can you do it for him? Input First line of the input consist an integer n , having 10 digits. In the second line you will be given an integer m , which is the sum of all 11 digits of the original number. Output Output a single line which is the original number. Constraints n is an integer of 10 digits, it is not guaranteed that this number doesn’t have leading zeros. m >= sum of all 10 digits of n. It is guaranteed that all inputs are valid and there is a solution of the problem. For better understanding see the sample input output. Example Input: 1234567890 50 Output: 51234567890

Sharmeen and the Lost Array (MOZSATLA) Sharmeen loves array very much. Many days ago she wrote an array (of n elements and the index of this array is 1 based) in her notebook, but unfortunately she lost the notebook. She want to restore the array. The only clue she know that is if in any position(i) of the array (1<= i < n), the element in this position is greater than, equal or less than the next position(i+1) element. Can you help her to restore the array? Input In the first line given an integer t (1 <= t <= 100), which is the number of test cases. For each test case, In the first line there will be given a positive integer n (1 <= n <= 10 5 ) which is the size of the lost array. In the next line there will be n - 1 integers X i (0 <= X i <= 2). If, X i = 0, then i th  element is equal to (i+1) th element of the lost array. If, X i = 1, then i th   element is less than (i+1) th element of the lost array. If, X i = 2, then i th  element is greater than (i+1) th element of the lost array. Output For each test case you have to output the lost array in one line. If multiple solution exist then you have to print the lexicographically smallest one. Elements of the lost array must be greater than zero . For better understanding see the sample input output. Example Input: 1 5 1 2 0 1 Output: 1 2 1 1 2

35,141
Sharmeen And Multiplication (MOZSAM) Sharmeen is a little girl who recently learned about multiplication. If she hears a number she multiplies it with the previous number. At first the multiplied result is 1. After that if anyone tells her a number she just multiplies it with the previous multiplied result. For example, at the beginning if someone tell 5, then she multiplies it with 1 and her multiplied result becomes 1*5 = 5. After that if anyone tells -2, she multiplies it with 5 and her result becomes 5 * (-2) = -10. This process continues. After doing this for several days Sharmeen thought how to get the maximum possible multiplied value? Then she realized that sometimes it is possible to get the maximum multiplied value if she skip some numbers to multiply and sometimes multiplying all the numbers is optimal to get the maximum multiplied value. So, you have the authority to skip some numbers. For example, in the above you can skip the second number, then the result will be 5, which is the maximum possible multiplied value in that case. Can you find an optimal way of selecting numbers in which multiplying the selected numbers will give you the maximum multiplied value of all possible way of selecting? You can skip all the numbers, if you do that then the result will be 1. You don’t have to print the way of selecting the numbers, just print the maximum multiplied value of the optimal way. Input You will be given an integer number n (0 <= n <= 9) which indicates how many numbers Sharmeen will hear. Then there will be n numbers x (-10 <= x <= 10). Output Print the maximum possible multiplied value in a line. Don’t forget to print new line after your answer. See the sample input output for better understanding. Example Input: 5 -3  2  -2  1  -3 Output: 18

Sharmeen and the distribution (MOZSATD) Sharmeen, the little girl has a friend named Mozahid. It is Eid day and they collect ‘Salami’s :P from their relatives. But as they are good friends, they want to divide the total amount of taka into two equal parts. But every time it is not possible, so they came with a solution. They can give any ‘salami’ to any poor people to help him, but there is a restriction. If they give a ‘salami’ to a poor, they have to give the whole ‘salami’. After helping the poor, they can add all the ‘salami’ amounts and divide it into two equal parts if possible, there is no restriction. But the divided amount must be integer. For example if the ‘salami’s are {3, 5, 1} you can’t divide (3+5+1)=9 into two equal parts. But if you give 5 taka to a poor people you can divide (3+1) = 4 into two equal parts 2 , 2. They want help the poor people(They are also allowed not to help any) in such a way that, the amount they get after dividing the remaining amount into two equal parts is maximum possible. Input The first line of the input is an integer n which is the number of ‘salami’s. The next line contains n integers A[i] which are the amount of each ‘salami’. Output Output the amount Sharmeen will get after distribution. Constrain: 1 <= n <= 10 5 1 <= A[i] <= 10 9 Example Input: 3 8 2 5 Output: 5 Explanation: As (8 + 2 + 5) = 15, which can’t be divided into two equal parts. They can give 5 taka to any poor people and divide the rest total into two equal parts. (8 + 2) = 10 , 10 / 2 = 5 . So, Sharmeen will get 5 taka.
35,154
Sharmeen and the commas (MOZSATC) Sharmeen the little girl recently learned about string. She found a long string from a book. The string contains characters from ‘a’ to ‘z’, ‘0’ to ‘9’ and commas(,). Now she wonder what will be the length of the largest substring of this string which will contain at most K commas? As she is not a programmer, can you do it for her? Input You will be given a string of length n( 1 <= n <= 10^5) in the first line. In the second line you will be given an integer K( 0 <= K <= n ), which is the maximum number of commas allowed in the expected substring. Output Output the length of the largest substring. Constrain: 1 <= n <= 10^5 0 <= k <= n Example Input: a,b,a0,3hg,0,,,sdfghijfh06 3 Output: 15 Explanation: The expected substring is “0,,,sdfghijfh06” which has a length of 15. There may be more than one optimal substring, but you don’t need to think about that, you have to just print the length of any optimal substring.
35,155
Sharmeen and parentheses (MOZSAPAR) Sharmeen the little girl learned about parentheses a few days ago. So as usual Mozahid gives her a problem to solve related to parentheses. As she is a little girl, she can’t find a solution. As you are a good programmer can you solve it for Sharmeen? You will be given a string consisting of only parentheses ‘(‘ or ‘)’ and question marks ‘?’. You can replace a question mark with an opening or closing parenthesis. If it is possible to make the string a valid parentheses sequence, output yes otherwise no. You have to replace all the question marks with parentheses . Input First line of the input is the number of test cases T (1 <= T <= 10^5). A string of length n (1 <= n <= 10^5) consisting of only ‘(‘ , ‘)‘ or ‘?’. Total length of all string will be at most 10^6. Output For each testcase, if it is possible to make the string a valid parentheses sequence replacing the ‘?’ marks with parentheses output ‘yes’ otherwise ‘no’ without quotes in one line. Constraints 1 <= T <= 10^5 1 <= n <= 10^5 Total length of all strings will be at most 10^6. See the sample input output for better understanding. Example Input: 2 (()??((??) ((?? Output: yes yes Explanation: Possible valid parentheses sequences for test case 1 are:- (())((())) (()()(()))

Sharmeen and the strange keyboard (MOZSATSK) Sharmeen’s grandfather had a strange long keyboard. The keyboard is so long that standing on a key of the keyboard sharmeen can only reach it’s adjacent at most two keys. You can think the keyboard as a string and every character in the string a key of the keyboard. So if she is now in position i of the string she can be able to reach only the positions i-1,i-2,i+1,i+2 if there exist such position of the string. The string contains only digits from ‘0’ to ‘9’ and any of these digits can appear more than once in this string. Though in real world there is no existence of such keyboard, you can think it is imaginary and just for solving problem with fun. Sharmeen has a limitation that she forget quickly and continuously. If now she know digit x , in the next minute she know only digit x , x-1 , x+1. If x = 0 then she know 0 , 9 , 1 in the next minute and if x = 9 , then she know 9, 8, 0 in the next minute. You can assume that she never press any key if she doesn’t know the digit of that key. She always know the first character of the string. After pressing a key she can press the next key exactly one minute later and pressing any key takes no time. You have to print ‘yes’ if she will be able to press the last key of the keyboard and minimum minutes required to press it. Otherwise print ‘no’ without quotes. Input A string S consists of only digits from ‘0’ to ‘9’ of length n( 1 <= n <= 10^5 ). Output Output your answer as mentioned above. Constrain: 1 <= n <= 10^5 See the sample input output for better understanding. Example Input: 5495 Output: yes 2 Explanation: At the beginning sharmeen presses S[0], it takes no time.

Sharmeen and counting letters (MOZSACL) Sharmeen is little girl but familiar with English letters. She is so expert that she is able to cope with any problem related with letters. So her friend Mozahid gives her a challenge to solve an interesting problem related with letters and she easily  solved it. As you are a good programmer can you do the same as Sharmeen? You are given an string of letters of length n (1 based index). At the beginning all the letters in that string are ‘#’. There exist two types of query: Update X V Query L R V Update X V: Find d, where d = lowest divisor of X which is greater than 1 and replace all the positions (d^1, d^2, d^3, d^4, …. ), with letter V. Query L R V: Find how many letter V are in the range of position L to R (inclusive). There will be q such type of query. Input First line contains the input string of length n, which contains only character ‘#’. Second line of the input is the number of query q. Then there will be q queries, which can be any of the two types mentioned above. Output For each query of type 2 output the number of occurrence of letter V in the range L to R(inclusive). See the sample input output for better understanding. Constrain: 1 <= n <= 10^5 1 <= q <= 10^5 2 <= X <= 10^7 1 <= L <= R <= n ‘a’ <= V <= ‘z’ Example Input: ########## 4 Query 1 5 a Update 2 a Query 1 5 a Query 8 8 a Output: 0 2 1

Valid Parentheses (MOZVAPA) Prangan Found a parentheses sequence while walking along the road of Comilla University. He wants to make the sequence as a valid parentheses sequence, because he learned it from his room-mate Mozahid last night. Prangan made the sequence valid very easily. But Mozahid now made it a bit tricky for Prangan. He told Prangan to make a substring of the sequence valid. He will give the left and the right position (L and R) of that substring. And he will ask it Q times. As Prangan is not good at Programming like you, he is seeking help from door to door. Please Help him. Note to mention that: a valid parentheses sequence is a parentheses sequence that can be transformed into a correct arithmetic expression by inserting characters "1" and "+" between the characters of the string. For example, parentheses sequences "()()", "(())" are correct (the resulting expressions "(1)+(1)", "((1+1)+1)"), and ")(" and "(" are not. Input The first line contains positive integer t (1 ≤ t ≤ 100) — the number of test cases. Each test case contains a positive integer N (1 <= N <= 100000), which is the length of parentheses sequence Prangan Found. Next Line contains a non-empty string S consisting of only characters '(', ')'. Next Line contains a positive integer Q (1 <= Q <= 100000) denotes the number of queries. In each query there will be two positive integer L and R (1 <= L <= R <= N). Summation of all N will not be greater than 500000. Output For each query you have to print "YES" if it is possible to make the sequence valid rearranging parentheses in between position L to R. See the sample output below for better understanding. Example Input: etc. Output: etc.

FEASTOFPIGS (MOMOS) The pig's are having a feast tonight!! There are N momos numbered from 0 to N - 1 . They are all arranged in a row on a table. Also K pigs are attending the feast. The j th pig has hunger a[j] . A pig with hunger a[j] only eats all momos with number i such that when i is divided by a[j] , the remainder is 0. For example, if there are 20 momos and a pig has hunger 3, then the pig will eat momos at position 0, 3, 6, 9, 12, 15, 18. Once a momo at a particular position is eaten by one pig, it cannot be eaten by a different pig. Your task is simple, given the number of momos, and hunger of K pigs, find the total number of momos left after the feast. Input The first line of the input contains two integers N and K , where N is the number of momos and K is the number of pigs. Lines 2, 3 ... K + 1 describe the hunger of K pigs. Line i + 1 (1 ≤ i ≤ K) contains a single integer representing the hunger of the i th pig (i.e. a[i] ). It is guaranteed that: either (1 ≤ N ≤ 10 6  and 1 ≤ K ≤ 100) or (1 ≤ N ≤ 10 14  and 1 ≤ K ≤ 20) The hunger of every pig lies between 1 and N . Output A line containing a single integer, which is the number of momos left on the table after all pigs have finished eating. Example Input: 20 3 3 6 5 Output: 11

Annual leave calculator (ALEAVE) In a large organisation, people need to keep track of annual leave. Employees will submit their leave requests, and these will be recorded. However, leave requests might overlap. A leave request has the form startday endday where startday and endday represent days of the year, falling between 1 and 366. Start day is the first day of the leave period (so counts as leave). End day is the day the leave ends - that is, the first day back in work. An employee will make any number of leave requests in a year, which might mistakenly overlap. At the end of the year you will need to calculate the total days leave for an employee based upon their requests. Requests can come out-of-order. Input Input will be the number of leave requests, followed by the set of leave requests, one per line. Output Output should be the total days leave requested for the employee in question Example Input: 3 140 145 120 123 121 122 Output: 8

Pizza and pigeons (PZZAPGON) You're delivering a lot of pizzas in a large city, laid out on a grid, and you have the instructions to get from each address to the next address in the following format: 2N 4W 3S 2E Assuming you start at 0,0 the above instructions would take you to 1S 2E (or -1,2 assuming negative values for W and S). At the end of your journey you have to send a message home by pigeon. How far does the pigeon have to fly?  Round up to the nearest integer. Input The first line of the input is the number of pizzas to deliver, N. N<100. The N subsequent lines contain directions from the previous pizza's location to the current pizza's location. Output A single number representing the distance that a pigeon would have to fly, to return to the pizza shop (the start of the mission). Round up to the nearest integer. Example Input: 3 4W 4N 3E 5S 2W 4N Output: 5

Abundant numbers (ABNDNTNM) An abundant number has factors that sum to more than itself; thus 12 is abundant as 1 + 2 + 3 + 4 + 6 = 16 > 12; so is 42 as 1 + 2 + 3 + 6 + 7 + 14 + 21 = 54 > 42.   Actually, this is an unusual property; write a program that given integers M and N computes the number of abundant numbers between M and N inclusive. Input One line of input featuring two integers M and N. M < N < 2 31 . Output A single integer on its own line, representing the count of abundant numbers between M and N. Example Input: 204 1007 Output: 201

Choosing staff to work on open days (OPNDYSTF) At university open days, we need to have a certain number of staff available - let's say we need R ambassadors to show people around and greet visitors.  There is a pool of N ambassadors that have signed up to work on open days. On a particular open day, how many possible combinations of R ambassadors can be drawn from a pool of N? For instance, if we need 2 ambassadors and there are 3 signed up (N=3, R=2) the answer would be 3. Input A single line of text with two integers, N and R. R<N<200 Output A single integer representing the number of possible combinations of ambassadors. Example Input: 10 3 Output: 120
