String Length

Version: Phuoc Hung OJ Extended

Problem Statement

You are given a text string $s$. Every letter, digit, punctuation mark, space, and tab counts as a character. A Unicode code point, including a precomposed Vietnamese character, counts once regardless of its UTF-8 byte length.

Determine the number of characters in $s$. Do not count the line terminator.

Input

The input consists of one line containing $s$. The line may be empty. Preserve all leading, trailing, and internal spaces.

Output

Print one integer: the number of characters in $s$ (its Python 3 string length).

Subtasks

• Subtask 1 (100 points): $0\le |s|\le 100$ Unicode characters.

Examples

A B

Output

3

Example 3

Input

Đắk Lắk

Output

7
