Write Python code to solve the task:
Taro is an elementary school student who has just learned multiplication. Somehow, he likes multiplication, so when he sees numbers, he wants to multiply. He seems to like to do the following for integers greater than or equal to 0. (Processing flow)
* Procedure 1. If a certain integer n greater than or equal to 0 is a single digit in decimal notation, the process ends there. Otherwise go to step 2
* Step 2. When an integer n of 10 or more is displayed in decimal, it is possible to break it into two numbers by inserting a break between some digits (for example, 2012-> 20, 12). For possible cutting methods like this, multiply the two obtained numbers and set the largest one as the next n, and return to step 1. (For details, see "Supplementary information on step 2" below.)
Taro seems to like this process, but I can't predict how many times step 2 should be repeated, and I think it may have to be done infinitely. So I asked Taro's older brother and college student how many times this step 2 should be done for an integer n greater than or equal to 0.
Your job is to give Q integers greater than or equal to 0 N1 .. NQ, so find out how many steps 2 will be performed on each integer before the end of the process. If you need an infinite number of steps, output -1.
Supplement on step 2
You should also take into account those that have a 0 at the beginning of the digit as a result of the isolation.
For example, when n = 1024, 1 * 024, 10 * 24, and 102 * 4 are calculated as 24,240,408, respectively, so 408 is selected and this is the next n.
Constraints
> 1 ≤ Q ≤ 100
> 0 ≤ Ni ≤ 106

Input
> Q

* Q represents the number of integers greater than or equal to 0 given
* Ni is an integer greater than or equal to 0 that Taro is interested in, and represents the i-th one.
Output
Output Q integers separated by line breaks
> R1

* Ri represents the number of times step 2 is executed before the processing is completed for Ni.
* Ri is -1 if step 2 needs to be performed infinitely for Ni

A right circular cone has base radius $r$ and height $h$. The cone lies on its side on a flat table. As the cone rolls on the surface of the table without slipping, the point where the cone's base meets the table traces a circular arc centered at the point where the vertex touches the table. The cone first returns to its original position on the table after making $17$ complete rotations. The value of $h/r$ can be written in the form $m\sqrt {n}$, where $m$ and $n$ are positive integers and $n$ is not divisible by the square of any prime. Find $m + n$. | [

Write Python code to solve the task:
Chef had an array A of length N such that 1 ≤ A_{i} ≤ N for all 1 ≤ i ≤ N. Chef constructed another binary array B of length N in the following manner:
B_{i} = 1 if the frequency of element i in A is *odd*.
B_{i} = 0 if the frequency of element i in A is *even*.
Such an array B is called the *parity encoding* array of A.
For example, if A = [1, 1, 2, 3], then B = [0, 1, 1, 0].
Unfortunately, Chef completely forgot the array A and vaguely remembers the *parity encoding* array B. He is now wondering whether there exists any valid array A for which the *parity encoding* array is B. Can you help Chef?
------ Input Format ------
- The first line contains a single integer T — the number of test cases. Then the test cases follow.
- The first line of each test case contains an integer N — the size of the arrays A and B.
- The second line of each test case contains N space-separated integers B_{1}, B_{2}, \dots, B_{N} denoting the *parity encoding* array B.
------ Output Format ------
For each test case, output YES if there exists any valid array A for which the *parity encoding* array is B. Otherwise, output NO.
You may print each character of YES and NO in uppercase or lowercase (for example, yes, yEs, Yes will be considered identical).
------ Constraints ------
$1 ≤ T ≤ 10^{5}$
$1 ≤ N ≤ 10^{5}$
$B_{i} \in \{0, 1\}$

Context:
Medical researcher: As expected, records covering the last four years of ten major hospitals indicate that babies born prematurely were more likely to have low birth weights and to suffer from health problems than were babies not born prematurely. These records also indicate that mothers who had received adequate prenatal care were less likely to have low birth weight babies than were mothers who had received inadequate prenatal care. Adequate prenatal care, ttherefore, significantly decreases the risk of low birth weight babies.
Question:
Which one of the following, if true, most weakens the medical researcher's argument?
Options:
A. The hospital records indicate that low birth weight babies were routinely classified as having been born prematurely.
B. Mothers giving birth prematurely are routinely classified by hospitals as having received inadequate prenatal care when the record of that care is not available.
C. The hospital records indicate that many babies that are born with normal birth weights are born to mothers who had inadequate prenatal care.
D. Women who receive adequate prenatal care, are less likely to give birth prematurely than are women who do not receive adequate prenatal care.

Context:
Several legislators claim that the public finds many current movies so sexually explicit as to be morally offensive. However, these legislators have misrepresented public opinion. In a survey conducted by a movie industry guild, only 15 percent of respondents think that movies are too sexually explicit, and only 4 percent found any recent movie to be morally offensive. These low percentages are telling because the respondents see far more current movies than does the average moviegoer.
Question:
The reasoning in the argument is flawed in that the argument
Options:
A. fails to consider the possibility that sexually explicit movies increase the prevalence of antisocial behavior
B. attempts to undermine the legislators' credibility instead of addressing their argument
C. generalizes from a sample that is unlikely to be representative of public sentiment
D. bases its conclusion on subjective judgments rather than on an objective criterion of moral offensiveness

Write Python code to solve the task:
Every great chef knows that lucky numbers are positive integers whose decimal representations contain only the lucky digits 4 and 7. For example, numbers 47, 744, 4 are lucky and 5, 17, 467 are not.
Our chef has recently returned from the Lucky country. He observed that every restaurant in the Lucky country had a lucky number as its name.
He believes that having a lucky number as a restaurant name can indeed turn out to be very lucky.
Our chef believes that it is possible to make a lucky number having N digits even luckier. Any number following the rules below is called Lucky lucky number -
1. The number contains only digits 4 and 7.
2. Count of digit 4 in the number should be divisible by 7.
3. Count of digit 7 in the number should be divisible by 4.
Help our chef to compute the count of digit 4 in the smallest Lucky lucky number having N digits.
Input
First line contains T, number of test cases. Each of the next T lines contains a number N, the number of digits in the Lucky lucky number to be formed.
1<=T<=1000
1<=N<=1000000000 (10^9)
Output
If it is not possible to form a Lucky lucky number having N digits, output -1.

Context:
The mainstream news media emphasize violence occurring in the Middle East at the expense of covering violence occurring in many other areas of the world. Although the media focus is on violence in the Middle East, the problem of violence is much greater in Central Africa. Yet the public tends to interpret the amount of coverage the media give to these occurrences as indicating the degree of the problem.
Question:
If the statements above are true, which one of the following conclusions is most strongly supported by them?
Options:
A. The emphasis given to violence in the Middle East is dictated by the public's interest in that region.
B. The Internet is more influential than print media in most areas of the world.

Context:
Psychologists have found that candidates for top political offices who blink excessively during televised debates are judged by viewers to have done less well than competing candidates who exhibit average blink rates. Any impact this phenomenon has on election results is surely deleterious: Many features -- knowledgeableness, confidence, and so forth -- contribute to a political official' s ability to perform well in office, but having an average blink rate is certainly not such a feature.
Question:
Which one of the following, if true, most weakens the argument?
Options:
A. Excessive blinking has been shown to be a mostly reliable indicator of a lack of confidence.
B. Blinking too infrequently during televised debates has the same effect on viewers' judgments of candidates as blinking excessively.
C. Viewers' judgments about candidates' debate performances are generally not affected by how knowledgeable the candidates appear to be.
D. Voters' judgments about candidates' debate performances rarely affect the results of national elections.

Write Python code to solve the task:
Two words are anagrams of one another if their letters can be rearranged to form the other word.
Given a string, split it into two contiguous substrings of equal length. Determine the minimum number of characters to change to make the two substrings into anagrams of one another.
Example
$s=\textbf{abccde}$
Break $\boldsymbol{\mathrm{~S~}}$ into two parts: 'abc' and 'cde'. Note that all letters have been used, the substrings are contiguous and their lengths are equal. Now you can change 'a' and 'b' in the first substring to 'd' and 'e' to have 'dec' and 'cde' which are anagrams. Two changes were necessary.
Function Description
Complete the anagram function in the editor below.
anagram has the following parameter(s):
string s: a string
Returns
int: the minimum number of characters to change or -1.
Input Format
The first line will contain an integer, $\textit{q}$, the number of test cases.
Each test case will contain a string $\boldsymbol{\mathrm{~S~}}$.
Constraints
$1\leq q\leq100$
$1\leq|s|\leq10^4$
$\boldsymbol{\mathrm{~S~}}$ consists only of characters in the range ascii[a-z].
Sample Input
6
aaabbb
ab
abc
mnop
xyyx
xaxbbbxx
Sample Output
3
1
-1
2
0
1
Explanation
Test Case #01: We split $\boldsymbol{\mathrm{~S~}}$ into two strings $\mbox{S1}$='aaa' and $\mbox{S2}$='bbb'. We have to replace all three characters from the first string with 'b' to make the strings anagrams.
Test Case #02: You have to replace 'a' with 'b', which will generate "bb".
Test Case #03: It is not possible for two strings of unequal length to be anagrams of one another.
Test Case #04: We have to replace both the characters of first string ("mn") to make it an anagram of the other one.
Test Case #05: $\mbox{S1}$ and $\mbox{S2}$ are already anagrams of one another.
Test Case #06: Here S1 = "xaxb" and S2 = "bbxx". You must replace 'a' from S1 with 'b' so that S1 = "xbxb". | [

Write Python code to solve the task:
Depth-first search (DFS) follows the strategy to search ”deeper” in the graph whenever possible. In DFS, edges are recursively explored out of the most recently discovered vertex $v$ that still has unexplored edges leaving it. When all of $v$'s edges have been explored, the search ”backtracks” to explore edges leaving the vertex from which $v$ was discovered.
This process continues until all the vertices that are reachable from the original source vertex have been discovered. If any undiscovered vertices remain, then one of them is selected as a new source and the search is repeated from that source.
DFS timestamps each vertex as follows:
* $d[v]$ records when $v$ is first discovered.
* $f[v]$ records when the search finishes examining $v$’s adjacency list.
Write a program which reads a directed graph $G = (V, E)$ and demonstrates DFS on the graph based on the following rules:
* $G$ is given in an adjacency-list. Vertices are identified by IDs $1, 2,... n$ respectively.
* IDs in the adjacency list are arranged in ascending order.
* The program should report the discover time and the finish time for each vertex.
* When there are several candidates to visit during DFS, the algorithm should select the vertex with the smallest ID.
* The timestamp starts with 1.
Constraints
* $1 \leq n \leq 100$
Input
In the first line, an integer $n$ denoting the number of vertices of $G$ is given. In the next $n$ lines, adjacency lists of $u$ are given in the following format:
$u$ $k$ $v_1$ $v_2$ ... $v_k$
$u$ is ID of the vertex and $k$ denotes its degree. $v_i$ are IDs of vertices adjacent to $u$.
Output
For each vertex, print $id$, $d$ and $f$ separated by a space character in a line. $id$ is ID of the vertex, $d$ and $f$ is the discover time and the finish time respectively. Print in order of vertex IDs.
