String Length

Read a string (single word, no spaces) and compute its length without using strlen(). Print the length.

Input

A single word (max 10^5 characters, no spaces).

Output

A single integer: the length of the string.

Examples

Input:  hello
Output: 5

Input:  C
Output: 1

Input:  12345
Output: 5

Digits are still just characters: the length count doesn't care what kind of characters they are.
