Everyone knows that there are ~26~ letters in the English alphabet. But can you calculate the position of any letter?

Given an uppercase letter, your task is to determine its position in the English alphabet.

Note: You may only submit to this problem in C/C++.

Input Specification

The first line of input contains a single uppercase letter ~c~.

Output Specification

Output on a single line, the position of the letter ~c~ in the alphabet. For example, A ~= 1,~ B ~= 2, \dots,~ Z ~= 26~.

Scoring

Your score will be computed based on the length of your source code, the shorter the better. For an ~L~-byte program,

• if ~L \le 36~, you will receive the full ~100~ points.
• if ~37 \le L~, you will receive ~\lfloor 2^{0.28(60-L)} \rfloor~ points.
