A14985 | Dictionary

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.

The first line contains one integer $t$ ( $1 \le t \le 650$ ) — the number of test cases.

Each test case consists of one line containing $s$ — a string consisting of exactly two different lowercase Latin letters (i. e. a correct word of the Berland language).

For each test case, print one integer — the index of the word $s$ in the dictionary.
