ABC Gene
There is a gene sequence represented by the string `ABC`. You can rewrite this gene sequence by performing the following operations several times.
* Choose one of the letters `A`,` B`, `C`. Let this be x. Replace all x in the gene sequence with `ABC` at the same time.
Given a string S consisting only of `A`,` B`, and `C`. Determine if the gene sequence can be matched to S.
Constraints
* 1 β€ | S | β€ 5,000
* S consists only of `A`,` B`, and `C`.
Input Format
Input is given from standard input in the following format.
S
Output Format
Output `Yes` if the gene sequence can be matched to S, and` No` if it cannot be matched.
Sample Input 1
ABC
Sample Output 1
Yes
The gene sequence is `ABC` from the beginning.
Sample Input 2
AABCC
Sample Output 2
Yes
If you select `B` and perform the operation, it becomes` ABC` β `AABCC`.
Sample Input 3
AABCABC
Sample Output 3
No
For example, even if you select `C` and perform an operation, it does not change from` AABCC` to `AABCABC`. Since all `C`s are replaced with` ABC` at the same time, the actual result is `AABCC` β` AABABCABC`.

While Mike was walking in the subway, all the stuff in his back-bag dropped on the ground. There were several fax messages among them. He concatenated these strings in some order and now he has string s.
<image>
He is not sure if this is his own back-bag or someone else's. He remembered that there were exactly k messages in his own bag, each was a palindrome string and all those strings had the same length.
He asked you to help him and tell him if he has worn his own back-bag. Check if the given string s is a concatenation of k palindromes of the same length.
Input
The first line of input contains string s containing lowercase English letters (1 β€ |s| β€ 1000).
The second line contains integer k (1 β€ k β€ 1000).

Arkady's code contains n variables. Each variable has a unique name consisting of lowercase English letters only. One day Arkady decided to shorten his code.
He wants to replace each variable name with its non-empty prefix so that these new names are still unique (however, a new name of some variable can coincide with some old name of another or same variable). Among such possibilities he wants to find the way with the smallest possible total length of the new names.
A string a is a prefix of a string b if you can delete some (possibly none) characters from the end of b and obtain a.
Please find this minimum possible total length of new names.
Input
The first line contains a single integer n (1 β€ n β€ 10^5) β the number of variables.
The next n lines contain variable names, one per line. Each name is non-empty and contains only lowercase English letters. The total length of these strings is not greater than 10^5. The variable names are distinct.
Output
Print a single integer β the minimum possible total length of new variable names.

Problem A: Swap crypto
A 2D enthusiast at R University, he often writes embarrassing sentences that blush when seen by people. Therefore, in order for a third party to not be able to see the text he is writing, he encrypts the text using a method called swap encryption that he devised independently. In swap encryption, the following steps are repeated N times to perform encryption.
1. Swap the ai and bi of the string
2. Return these two characters in alphabetical order by the difference between ai and bi
However, in alphabetical order, "z" is used before "a".
For example, if the character string "aojwo" is encrypted with a1 = 1 and b1 = 4, it will be as follows.
1. Swap the 1st and 4th ("aojwo" β "wojao")
2. Return these two letters'w'and'a' in alphabetical order by the difference between 1 and 4 = 3 ("wojao"-> "tojxo")
* If'w'is returned by 3 in alphabetical order, it becomes'w' β'v' β'u' β't'.
* If'a'is returned by 3 in alphabetical order, it becomes'a' β'z' β'y' β'x'.
Therefore, "aojwo" is encrypted as "tojxo".
This encryption should have allowed him to encrypt his text without knowing the original text, but perhaps he leaked the swap operation process he used to encrypt it. Your job is to create a program that "decrypts" given the encrypted strings and the swap operation used for encryption, and dismisses him as a 2D enthusiast.
Input
The input consists of multiple datasets. The total number of datasets is 20 or less. Each dataset has the following format:
N

a1 b1
...
ai bi
...
aN bN
N (0 <N β€ 100) is an integer that indicates the number of swap operations when encrypting. message indicates encrypted data. Cryptographic data is a character string consisting of only lowercase letters of the alphabet. If the length of the message is len, we can assume that 2 β€ len β€ 100.
ai and bi represent two indexes that have been swapped in encryption. You can assume that 1 β€ ai <bi β€ len. For encryption, it is assumed that the swap operations are performed in the order in which they are entered.
The end of the input is indicated by a single line consisting of only 0s. This data does not need to be processed.
Output
Output the decrypted string on one line for each dataset.

Provide a correct Python 3 solution for this coding contest problem.
A gene is a string consisting of `A`,` T`, `G`,` C`. The genes in this world are strangely known to obey certain syntactic rules.
Syntax rules are given in the following form:
Non-terminal symbol 1: Symbol 1_1 Symbol 1_2 ... Symbol 1_n1
Non-terminal symbol 2: Symbol 2_1 Symbol 2_2 ... Symbol 2_n2
...
Non-terminal symbol m: symbol m_1 symbol m_2 ... symbol m_nm
The symbol is either a nonterminal symbol or a terminal symbol. Non-terminal symbols are represented by lowercase strings, and terminal symbols are some of the characters `A`,` T`, `G`,` C` surrounded by "` [` "and" `]` ". It is represented by a character string.
An example syntax rule looks like this:
dna: a a b b
a: [AT]
b: [GC]
"` Nonterminal symbol i: Symbol i_1 Symbol i_2 ... Symbol i_ni` "is called a rule for nonterminal symbol i, and there is exactly one rule for each nonterminal symbol that appears in the syntax rule.
A string s "` matches `" with the nonterminal i means that there is a substring {sj} of s such that s = s1 + s2 + ... + sni, and sj (1 β€ j β€ It means that ni) matches the symbol j in the rule.
When the string s "` matches `" with a terminal symbol, it means that the string consists of one character and that character is included in the string representing the terminal symbol.
A string that follows syntax rules means that it matches nonterminal symbol 1.
Rule i does not include the nonterminal symbol j (j β€ i) in the symbol.
Given the syntax rules and the four integers Na, Nt, Ng, Nc. According to the syntax rules, find the remainder of the total number of genes that contain exactly Na for A, just Nt for T, just Ng for G, and just Nc for C, divided by 1,000,000,007.
Input
> Na Nt Ng Nc
> m
> Nonterminal 1: Symbol 11 Symbol 12 ... Symbol 1n1

1 β€ m β€ 50
1 β€ ni β€ 10
1 β€ Length of the character string representing the symbol β€ 20 (* Note that it is not the length of the character string that matches the symbol)

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
A gene is a string consisting of `A`,` T`, `G`,` C`. The genes in this world are strangely known to obey certain syntactic rules.
Syntax rules are given in the following form:
Non-terminal symbol 1: Symbol 1_1 Symbol 1_2 ... Symbol 1_n1
Non-terminal symbol 2: Symbol 2_1 Symbol 2_2 ... Symbol 2_n2
...
Non-terminal symbol m: symbol m_1 symbol m_2 ... symbol m_nm
The symbol is either a nonterminal symbol or a terminal symbol. Non-terminal symbols are represented by lowercase strings, and terminal symbols are some of the characters `A`,` T`, `G`,` C` surrounded by "` [` "and" `]` ". It is represented by a character string.
An example syntax rule looks like this:
dna: a a b b
a: [AT]
b: [GC]
"` Nonterminal symbol i: Symbol i_1 Symbol i_2 ... Symbol i_ni` "is called a rule for nonterminal symbol i, and there is exactly one rule for each nonterminal symbol that appears in the syntax rule.
A string s "` matches `" with the nonterminal i means that there is a substring {sj} of s such that s = s1 + s2 + ... + sni, and sj (1 β€ j β€ It means that ni) matches the symbol j in the rule.
When the string s "` matches `" with a terminal symbol, it means that the string consists of one character and that character is included in the string representing the terminal symbol.
A string that follows syntax rules means that it matches nonterminal symbol 1.
Rule i does not include the nonterminal symbol j (j β€ i) in the symbol.
Given the syntax rules and the four integers Na, Nt, Ng, Nc. According to the syntax rules, find the remainder of the total number of genes that contain exactly Na for A, just Nt for T, just Ng for G, and just Nc for C, divided by 1,000,000,007.
Input
