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.
