Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Innokentiy decides to change the password in the social net "Contact!", but he is too lazy to invent a new password by himself. That is why he needs your help.
Innokentiy decides that new password should satisfy the following conditions:
* the length of the password must be equal to n,
* the password should consist only of lowercase Latin letters,
* the number of distinct symbols in the password must be equal to k,
* any two consecutive symbols in the password must be distinct.
Your task is to help Innokentiy and to invent a new password which will satisfy all given conditions.
Input
The first line contains two positive integers n and k (2 β€ n β€ 100, 2 β€ k β€ min(n, 26)) β the length of the password and the number of distinct symbols in it.
Pay attention that a desired new password always exists.
Output
Print any password which satisfies all conditions given by Innokentiy.

Note
In the first test there is one of the appropriate new passwords β java, because its length is equal to 4 and 3 distinct lowercase letters a, j and v are used in it.
In the second test there is one of the appropriate new passwords β python, because its length is equal to 6 and it consists of 6 distinct lowercase letters.
In the third test there is one of the appropriate new passwords β phphp, because its length is equal to 5 and 2 distinct lowercase letters p and h are used in it.
Pay attention the condition that no two identical symbols are consecutive is correct for all appropriate passwords in tests.

Vitya has just started learning Berlanese language. It is known that Berlanese uses the Latin alphabet. Vowel letters are "a", "o", "u", "i", and "e". Other letters are consonant.
In Berlanese, there has to be a vowel after every consonant, but there can be any letter after any vowel. The only exception is a consonant "n"; after this letter, there can be any letter (not only a vowel) or there can be no letter at all. For example, the words "harakiri", "yupie", "man", and "nbo" are Berlanese while the words "horse", "king", "my", and "nz" are not.
Help Vitya find out if a word s is Berlanese.
Input
The first line of the input contains the string s consisting of |s| (1β€ |s|β€ 100) lowercase Latin letters.
Output
Print "YES" (without quotes) if there is a vowel after every consonant except "n", otherwise print "NO".
You can print each letter in any case (upper or lower).
Examples
Input
sumimasen
Output
YES
Input
ninja
Output
YES
Input
codeforces
Output

Note
In the first and second samples, a vowel goes after each consonant except "n", so the word is Berlanese.
In the third sample, the consonant "c" goes after the consonant "r", and the consonant "s" stands on the end, so the word is not Berlanese.

Homer has two friends Alice and Bob. Both of them are string fans.
One day, Alice and Bob decide to play a game on a string s = s_1 s_2 ... s_n of length n consisting of lowercase English letters. They move in turns alternatively and Alice makes the first move.
In a move, a player must choose an index i (1 β€ i β€ n) that has not been chosen before, and change s_i to any other lowercase English letter c that c β s_i.
When all indices have been chosen, the game ends.
The goal of Alice is to make the final string lexicographically as small as possible, while the goal of Bob is to make the final string lexicographically as large as possible. Both of them are game experts, so they always play games optimally. Homer is not a game expert, so he wonders what the final string will be.
A string a is lexicographically smaller than a string b if and only if one of the following holds:
* a is a prefix of b, but a β b;
* in the first position where a and b differ, the string a has a letter that appears earlier in the alphabet than the corresponding letter in b.
Input
Each test contains multiple test cases. The first line contains t (1 β€ t β€ 1000) β the number of test cases. Description of the test cases follows.
The only line of each test case contains a single string s (1 β€ |s| β€ 50) consisting of lowercase English letters.
Output
For each test case, print the final string in a single line.
Example
Input
3
a
bbbb
az
Output
b
azaz
by
Note
In the first test case: Alice makes the first move and must change the only letter to a different one, so she changes it to 'b'.
In the second test case: Alice changes the first letter to 'a', then Bob changes the second letter to 'z', Alice changes the third letter to 'a' and then Bob changes the fourth letter to 'z'.
In the third test case: Alice changes the first letter to 'b', and then Bob changes the second letter to 'y'.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Homer has two friends Alice and Bob. Both of them are string fans.
One day, Alice and Bob decide to play a game on a string s = s_1 s_2 ... s_n of length n consisting of lowercase English letters. They move in turns alternatively and Alice makes the first move.
In a move, a player must choose an index i (1 β€ i β€ n) that has not been chosen before, and change s_i to any other lowercase English letter c that c β s_i.
When all indices have been chosen, the game ends.
The goal of Alice is to make the final string lexicographically as small as possible, while the goal of Bob is to make the final string lexicographically as large as possible. Both of them are game experts, so they always play games optimally. Homer is not a game expert, so he wonders what the final string will be.
A string a is lexicographically smaller than a string b if and only if one of the following holds:
* a is a prefix of b, but a β b;
* in the first position where a and b differ, the string a has a letter that appears earlier in the alphabet than the corresponding letter in b.

The problem describes the properties of a command line. The description somehow resembles the one you usually see in real operating systems. However, there are differences in the behavior. Please make sure you've read the statement attentively and use it as a formal document.
In the Pindows operating system a strings are the lexemes of the command line β the first of them is understood as the name of the program to run and the following lexemes are its arguments. For example, as we execute the command " run.exe one, two . ", we give four lexemes to the Pindows command line: "run.exe", "one,", "two", ".". More formally, if we run a command that can be represented as string s (that has no quotes), then the command line lexemes are maximal by inclusion substrings of string s that contain no spaces.
To send a string with spaces or an empty string as a command line lexeme, we can use double quotes. The block of characters that should be considered as one lexeme goes inside the quotes. Embedded quotes are prohibited β that is, for each occurrence of character """ we should be able to say clearly that the quotes are opening or closing. For example, as we run the command ""run.exe o" "" " ne, " two . " " ", we give six lexemes to the Pindows command line: "run.exe o", "" (an empty string), " ne, ", "two", ".", " " (a single space).
It is guaranteed that each lexeme of the command line is either surrounded by spaces on both sides or touches the corresponding command border. One of its consequences is: the opening brackets are either the first character of the string or there is a space to the left of them.
You have a string that consists of uppercase and lowercase English letters, digits, characters ".,?!"" and spaces. It is guaranteed that this string is a correct OS Pindows command line string. Print all lexemes of this command line string. Consider the character """ to be used only in order to denote a single block of characters into one command line lexeme. In particular, the consequence is that the given string has got an even number of such characters.
Input
The single line contains a non-empty string s. String s consists of at most 105 characters. Each character is either an uppercase or a lowercase English letter, or a digit, or one of the ".,?!"" signs, or a space.
It is guaranteed that the given string is some correct command line string of the OS Pindows. It is guaranteed that the given command line string contains at least one lexeme.
Output
In the first line print the first lexeme, in the second line print the second one and so on. To make the output clearer, print the "<" (less) character to the left of your lexemes and the ">" (more) character to the right. Print the lexemes in the order in which they occur in the command.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
The problem describes the properties of a command line. The description somehow resembles the one you usually see in real operating systems. However, there are differences in the behavior. Please make sure you've read the statement attentively and use it as a formal document.
In the Pindows operating system a strings are the lexemes of the command line β the first of them is understood as the name of the program to run and the following lexemes are its arguments. For example, as we execute the command " run.exe one, two . ", we give four lexemes to the Pindows command line: "run.exe", "one,", "two", ".". More formally, if we run a command that can be represented as string s (that has no quotes), then the command line lexemes are maximal by inclusion substrings of string s that contain no spaces.
To send a string with spaces or an empty string as a command line lexeme, we can use double quotes. The block of characters that should be considered as one lexeme goes inside the quotes. Embedded quotes are prohibited β that is, for each occurrence of character """ we should be able to say clearly that the quotes are opening or closing. For example, as we run the command ""run.exe o" "" " ne, " two . " " ", we give six lexemes to the Pindows command line: "run.exe o", "" (an empty string), " ne, ", "two", ".", " " (a single space).
It is guaranteed that each lexeme of the command line is either surrounded by spaces on both sides or touches the corresponding command border. One of its consequences is: the opening brackets are either the first character of the string or there is a space to the left of them.
