Problem Statement

You are given a string $S$ consisting of uppercase and lowercase English letters.
Here, exactly one character of $S$ is uppercase, and the others are all lowercase.
Find the integer $x$ such that the $x$-th character of $S$ is uppercase.
Here, the initial character of $S$ is considered the $1$-st one.

• $S$ is a string of length between $2$ and $100$, inclusive, consisting of uppercase and lowercase English letters.
• $S$ has exactly one uppercase letter.

Input

The input is given from Standard Input in the following format:

$S$

Output

Print the integer $x$ such that the $x$-th character of $S$ is uppercase.

Sample Input 1

aBc

Sample Output 1

2

The $1$-st character of aBc is a, the $2$-nd is B, and the $3$-rd is c; the $2$-nd character is uppercase.
Thus, $2$ should be printed.
