Provide tags and a correct Python 3 solution for this coding contest problem. There are n people sitting in a circle, numbered from 1 to n in the order in which they are seated. That is, for all i from 1 to n-1, the people with id i and i+1 are adjacent. People with id n and 1 are adjacent as well. The person with id 1 initially has a ball. He picks a positive integer k at most n, and passes the ball to his k-th neighbour in the direction of increasing ids, that person passes the ball to his k-th neighbour in the same direction, and so on until the person with the id 1 gets the ball back. When he gets it back, people do not pass the ball any more. For instance, if n = 6 and k = 4, the ball is passed in order [1, 5, 3, 1]. Consider the set of all people that touched the ball. The fun value of the game is the sum of the ids of people that touched it. In the above example, the fun value would be 1 + 5 + 3 = 9. Find and report the set of possible fun values for all choices of positive integer k. It can be shown that under the constraints of the problem, the ball always gets back to the 1-st player after finitely many steps, and there are no more than 10^5 possible fun values for given n. Input The only line consists of a single integer n (2 ≤ n ≤ 10^9) — the number of people playing with the ball. Output Suppose the set of all fun values is f_1, f_2, ..., f_m. Output a single line containing m space separated integers f_1 through f_m in increasing order. Examples Input 6 Output 1 5 9 21 Input 16 Output 1 10 28 64 136 Note In the first sample, we've already shown that picking k = 4 yields fun value 9, as does k = 2. Picking k = 6 results in fun value of 1. For k = 3 we get fun value 5 and with k = 1 or k = 5 we get 21. <image> In the second sample, the values 1, 10, 28, 64 and 136 are achieved for instance for k = 16, 8, 4, 10 and 11, respectively.

When he gets it back, people do not pass the ball any more. For instance, if n = 6 and k = 4, the ball is passed in order [1, 5, 3, 1]. Consider the set of all people that touched the ball. The fun value of the game is the sum of the ids of people that touched it. In the above example, the fun value would be 1 + 5 + 3 = 9. Find and report the set of possible fun values for all choices of positive integer k. It can be shown that under the constraints of the problem, the ball always gets back to the 1-st player after finitely many steps, and there are no more than 10^5 possible fun values for given n. Input The only line consists of a single integer n (2 ≤ n ≤ 10^9) — the number of people playing with the ball. Output Suppose the set of all fun values is f_1, f_2, ..., f_m. Output a single line containing m space separated integers f_1 through f_m in increasing order. Examples Input 6 Output 1 5 9 21 Input 16 Output 1 10 28 64 136 Note In the first sample, we've already shown that picking k = 4 yields fun value 9, as does k = 2. Picking k = 6 results in fun value of 1. For k = 3 we get fun value 5 and with k = 1 or k = 5 we get 21. <image> In the second sample, the values 1, 10, 28, 64 and 136 are achieved for instance for k = 16, 8, 4, 10 and 11, respectively. Submitted Solution: ``` n = int(input()) a = set([]) i = 1 while i*i <= n: if(n%i == 0): x = i y = n//i # 1+x+1+2x+1+....+(y-1)x+1 # y + (y)(y-1)(x)/2 a.add(y+(((y)*(y-1)*(x))/2)) x,y = y,x a.add(y+(((y)*(y-1)*(x))/2)) i += 1 a = sorted(list(a)) for i in a: print(int(i),end=' ') print() ```

Provide tags and a correct Python 3 solution for this coding contest problem. Vasya has a pack of 54 cards (52 standard cards and 2 distinct jokers). That is all he has at the moment. Not to die from boredom, Vasya plays Solitaire with them. Vasya lays out nm cards as a rectangle n × m. If there are jokers among them, then Vasya should change them with some of the rest of 54 - nm cards (which are not layed out) so that there were no jokers left. Vasya can pick the cards to replace the jokers arbitrarily. Remember, that each card presents in pack exactly once (i. e. in a single copy). Vasya tries to perform the replacements so that the solitaire was solved. Vasya thinks that the solitaire is solved if after the jokers are replaced, there exist two non-overlapping squares 3 × 3, inside each of which all the cards either have the same suit, or pairwise different ranks. Determine by the initial position whether the solitaire can be solved or not. If it can be solved, show the way in which it is possible. Input The first line contains integers n and m (3 ≤ n, m ≤ 17, n × m ≤ 52). Next n lines contain m words each. Each word consists of two letters. The jokers are defined as "J1" and "J2" correspondingly. For the rest of the cards, the first letter stands for the rank and the second one — for the suit. The possible ranks are: "2", "3", "4", "5", "6", "7", "8", "9", "T", "J", "Q", "K" and "A". The possible suits are: "C", "D", "H" and "S". All the cards are different. Output If the Solitaire can be solved, print on the first line "Solution exists." without the quotes. On the second line print in what way the jokers can be replaced. Three variants are possible: * "There are no jokers.", if there are no jokers in the input data. * "Replace Jx with y.", if there is one joker. x is its number, and y is the card it should be replaced with. * "Replace J1 with x and J2 with y.", if both jokers are present in the input data. x and y here represent distinct cards with which one should replace the first and the second jokers correspondingly. On the third line print the coordinates of the upper left corner of the first square 3 × 3 in the format "Put the first square to (r, c).", where r and c are the row and the column correspondingly. In the same manner print on the fourth line the coordinates of the second square 3 × 3 in the format "Put the second square to (r, c).". If there are several solutions to that problem, print any of them. If there are no solutions, print of the single line "No solution." without the quotes. See the samples to understand the output format better. Examples Input 4 6 2S 3S 4S 7S 8S AS 5H 6H 7H 5S TC AC 8H 9H TH 7C 8C 9C 2D 2C 3C 4C 5C 6C Output No solution.

Provide tags and a correct Python 3 solution for this coding contest problem. Vasya has a pack of 54 cards (52 standard cards and 2 distinct jokers). That is all he has at the moment. Not to die from boredom, Vasya plays Solitaire with them. Vasya lays out nm cards as a rectangle n × m. If there are jokers among them, then Vasya should change them with some of the rest of 54 - nm cards (which are not layed out) so that there were no jokers left. Vasya can pick the cards to replace the jokers arbitrarily. Remember, that each card presents in pack exactly once (i. e. in a single copy). Vasya tries to perform the replacements so that the solitaire was solved. Vasya thinks that the solitaire is solved if after the jokers are replaced, there exist two non-overlapping squares 3 × 3, inside each of which all the cards either have the same suit, or pairwise different ranks. Determine by the initial position whether the solitaire can be solved or not. If it can be solved, show the way in which it is possible. Input The first line contains integers n and m (3 ≤ n, m ≤ 17, n × m ≤ 52). Next n lines contain m words each. Each word consists of two letters. The jokers are defined as "J1" and "J2" correspondingly. For the rest of the cards, the first letter stands for the rank and the second one — for the suit. The possible ranks are: "2", "3", "4", "5", "6", "7", "8", "9", "T", "J", "Q", "K" and "A". The possible suits are: "C", "D", "H" and "S". All the cards are different. Output If the Solitaire can be solved, print on the first line "Solution exists." without the quotes. On the second line print in what way the jokers can be replaced. Three variants are possible: * "There are no jokers.", if there are no jokers in the input data. * "Replace Jx with y.", if there is one joker. x is its number, and y is the card it should be replaced with. * "Replace J1 with x and J2 with y.", if both jokers are present in the input data. x and y here represent distinct cards with which one should replace the first and the second jokers correspondingly. On the third line print the coordinates of the upper left corner of the first square 3 × 3 in the format "Put the first square to (r, c).", where r and c are the row and the column correspondingly. In the same manner print on the fourth line the coordinates of the second square 3 × 3 in the format "Put the second square to (r, c).". If there are several solutions to that problem, print any of them. If there are no solutions, print of the single line "No solution." without the quotes. See the samples to understand the output format better. Examples Input 4 6 2S 3S 4S 7S 8S AS 5H 6H 7H 5S TC AC 8H 9H TH 7C 8C 9C 2D 2C 3C 4C 5C 6C Output No solution.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Vasya has a pack of 54 cards (52 standard cards and 2 distinct jokers). That is all he has at the moment. Not to die from boredom, Vasya plays Solitaire with them. Vasya lays out nm cards as a rectangle n × m. If there are jokers among them, then Vasya should change them with some of the rest of 54 - nm cards (which are not layed out) so that there were no jokers left. Vasya can pick the cards to replace the jokers arbitrarily. Remember, that each card presents in pack exactly once (i. e. in a single copy). Vasya tries to perform the replacements so that the solitaire was solved. Vasya thinks that the solitaire is solved if after the jokers are replaced, there exist two non-overlapping squares 3 × 3, inside each of which all the cards either have the same suit, or pairwise different ranks. Determine by the initial position whether the solitaire can be solved or not. If it can be solved, show the way in which it is possible. Input The first line contains integers n and m (3 ≤ n, m ≤ 17, n × m ≤ 52). Next n lines contain m words each. Each word consists of two letters. The jokers are defined as "J1" and "J2" correspondingly. For the rest of the cards, the first letter stands for the rank and the second one — for the suit. The possible ranks are: "2", "3", "4", "5", "6", "7", "8", "9", "T", "J", "Q", "K" and "A". The possible suits are: "C", "D", "H" and "S". All the cards are different. Output If the Solitaire can be solved, print on the first line "Solution exists." without the quotes. On the second line print in what way the jokers can be replaced. Three variants are possible: * "There are no jokers.", if there are no jokers in the input data. * "Replace Jx with y.", if there is one joker. x is its number, and y is the card it should be replaced with. * "Replace J1 with x and J2 with y.", if both jokers are present in the input data. x and y here represent distinct cards with which one should replace the first and the second jokers correspondingly. On the third line print the coordinates of the upper left corner of the first square 3 × 3 in the format "Put the first square to (r, c).", where r and c are the row and the column correspondingly. In the same manner print on the fourth line the coordinates of the second square 3 × 3 in the format "Put the second square to (r, c).". If there are several solutions to that problem, print any of them. If there are no solutions, print of the single line "No solution." without the quotes. See the samples to understand the output format better. Examples Input 4 6 2S 3S 4S 7S 8S AS 5H 6H 7H 5S TC AC 8H 9H TH 7C 8C 9C 2D 2C 3C 4C 5C 6C Output No solution.

Vasya thinks that the solitaire is solved if after the jokers are replaced, there exist two non-overlapping squares 3 × 3, inside each of which all the cards either have the same suit, or pairwise different ranks. Determine by the initial position whether the solitaire can be solved or not. If it can be solved, show the way in which it is possible. Input The first line contains integers n and m (3 ≤ n, m ≤ 17, n × m ≤ 52). Next n lines contain m words each. Each word consists of two letters. The jokers are defined as "J1" and "J2" correspondingly. For the rest of the cards, the first letter stands for the rank and the second one — for the suit. The possible ranks are: "2", "3", "4", "5", "6", "7", "8", "9", "T", "J", "Q", "K" and "A". The possible suits are: "C", "D", "H" and "S". All the cards are different. Output If the Solitaire can be solved, print on the first line "Solution exists." without the quotes. On the second line print in what way the jokers can be replaced. Three variants are possible: * "There are no jokers.", if there are no jokers in the input data. * "Replace Jx with y.", if there is one joker. x is its number, and y is the card it should be replaced with. * "Replace J1 with x and J2 with y.", if both jokers are present in the input data. x and y here represent distinct cards with which one should replace the first and the second jokers correspondingly. On the third line print the coordinates of the upper left corner of the first square 3 × 3 in the format "Put the first square to (r, c).", where r and c are the row and the column correspondingly. In the same manner print on the fourth line the coordinates of the second square 3 × 3 in the format "Put the second square to (r, c).". If there are several solutions to that problem, print any of them. If there are no solutions, print of the single line "No solution." without the quotes. See the samples to understand the output format better. Examples Input 4 6 2S 3S 4S 7S 8S AS 5H 6H 7H 5S TC AC 8H 9H TH 7C 8C 9C 2D 2C 3C 4C 5C 6C Output No solution.

Provide tags and a correct Python 3 solution for this coding contest problem. Yakko, Wakko and Dot, world-famous animaniacs, decided to rest from acting in cartoons, and take a leave to travel a bit. Yakko dreamt to go to Pennsylvania, his Motherland and the Motherland of his ancestors. Wakko thought about Tasmania, its beaches, sun and sea. Dot chose Transylvania as the most mysterious and unpredictable place. But to their great regret, the leave turned to be very short, so it will be enough to visit one of the three above named places. That's why Yakko, as the cleverest, came up with a truly genius idea: let each of the three roll an ordinary six-sided die, and the one with the highest amount of points will be the winner, and will take the other two to the place of his/her dreams. Yakko thrown a die and got Y points, Wakko — W points. It was Dot's turn. But she didn't hurry. Dot wanted to know for sure what were her chances to visit Transylvania. It is known that Yakko and Wakko are true gentlemen, that's why if they have the same amount of points with Dot, they will let Dot win. Input The only line of the input file contains two natural numbers Y and W — the results of Yakko's and Wakko's die rolls. Output Output the required probability in the form of irreducible fraction in format «A/B», where A — the numerator, and B — the denominator. If the required probability equals to zero, output «0/1». If the required probability equals to 1, output «1/1». Examples Input 4 2 Output 1/2 Note Dot will go to Transylvania, if she is lucky to roll 4, 5 or 6 points.

Yakko thrown a die and got Y points, Wakko — W points. It was Dot's turn. But she didn't hurry. Dot wanted to know for sure what were her chances to visit Transylvania. It is known that Yakko and Wakko are true gentlemen, that's why if they have the same amount of points with Dot, they will let Dot win. Input The only line of the input file contains two natural numbers Y and W — the results of Yakko's and Wakko's die rolls. Output Output the required probability in the form of irreducible fraction in format «A/B», where A — the numerator, and B — the denominator. If the required probability equals to zero, output «0/1». If the required probability equals to 1, output «1/1». Examples Input 4 2 Output 1/2 Note Dot will go to Transylvania, if she is lucky to roll 4, 5 or 6 points. Submitted Solution: ``` temp = [int(x) for x in input().split()] y = temp[0] w = temp[1] d = 6-(max(y, w)-1) if d == 0 or d == 6: print(str(d%5) + '/1') elif d%2 == 0: print(str(d//2) + '/3') elif d == 5: print('5/6') else: print('1/2') ```

Yakko, Wakko and Dot, world-famous animaniacs, decided to rest from acting in cartoons, and take a leave to travel a bit. Yakko dreamt to go to Pennsylvania, his Motherland and the Motherland of his ancestors. Wakko thought about Tasmania, its beaches, sun and sea. Dot chose Transylvania as the most mysterious and unpredictable place. But to their great regret, the leave turned to be very short, so it will be enough to visit one of the three above named places.

Provide a correct Python 3 solution for this coding contest problem. Consider the following game: * The game is played using a row of N squares and many stones. * First, a_i stones are put in Square i\ (1 \leq i \leq N). * A player can perform the following operation as many time as desired: "Select an integer i such that Square i contains exactly i stones. Remove all the stones from Square i, and add one stone to each of the i-1 squares from Square 1 to Square i-1." * The final score of the player is the total number of the stones remaining in the squares. For a sequence a of length N, let f(a) be the minimum score that can be obtained when the game is played on a. Find the sum of f(a) over all sequences a of length N where each element is between 0 and K (inclusive). Since it can be extremely large, find the answer modulo 1000000007 (= 10^9+7). Constraints * 1 \leq N \leq 100 * 1 \leq K \leq N Input Input is given from Standard Input in the following format: N K Output Print the sum of f(a) modulo 1000000007 (= 10^9+7).

Example Input 6 2 1 1 2 3 0 2 3 7 2 -1 31415926 27182818 2 1000000000000000000 1 1000000000000000000 2 -1000000000000000000 -1000000000000000000 123 6 80 -5 -20 13 -14 -2 -11 Output YES YES NO YES YES NO Note In the first test case, the number 1 is already on the board. In the second test case, Nezzar could perform the following operations to write down k=0 on the board: * Select x=3 and y=2 and write down 4 on the board. * Select x=4 and y=7 and write down 1 on the board. * Select x=1 and y=2 and write down 0 on the board. In the third test case, it is impossible to have the number k = -1 on the board. Submitted Solution: ``` cases=int(input()) inp=[] for i in range(cases*2): inp.append([int(x) for x in input().split(" ")]) print(inp) for i in range(0,len(inp),2): k=inp[i][1] board=inp[i+1] true=True if k in board else False even=0 odd=0 for i in board: if i>=0 and i%2==0: even+=1 elif i>=0: odd=1 if true: print("Yes") elif even>=1 and odd>=1: print("Yes") else: print("No") ```
