题目描述
The Berland language consists of words having exactly two letters. Moreover, the first letter of a word is different from the second letter. Any combination of two different Berland letters (which, by the way, are the same as the lowercase letters of Latin alphabet) is a correct word in Berland language.
The Berland dictionary contains all words of this language. The words are listed in a way they are usually ordered in dictionaries. Formally, word $a$ comes earlier than word $b$ in the dictionary if one of the following conditions hold:
- the first letter of $a$ is less than the first letter of $b$ ;
- the first letters of $a$ and $b$ are the same, and the second letter of $a$ is less than the second letter of $b$ .
So, the dictionary looks like that:
- Word $1$ : ab
- Word $2$ : ac
- ...
- Word $25$ : az
- Word $26$ : ba
- Word $27$ : bc
- ...
- Word $649$ : zx
- Word $650$ : zy
You are given a word $s$ from the Berland language. Your task is to find its index in the dictionary.
