Description:

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.

Input:

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).

Output:

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

Sample Input:

7
ab
ac
az
ba
bc
zx
zy

Sample Output:

1
2
25
26
27
649
650
