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.

提示

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.
An uppercase letter $X$ occurs as the $7$-th character of $S=$$xxxxxxXxxx$, so $7$ should be printed.
