Integer with Leading Zeroes

Source: Phước Hưng OJ

Version: Phuoc Hung OJ Extended

Problem Statement

A non-negative integer NN is represented by a digit string SS, possibly with multiple leading zeroes. Print NN in its ordinary decimal representation without unnecessary leading zeroes. If N=0N=0, print exactly 0.

Input

One line containing the digit string SS representing a non-negative integer.

Output

Print the value NN in its canonical decimal representation.

Subtasks

  • Subtask 1 — 100 points: 1≤∣S∣≤1001\le |S|\le100; every character of SS is a digit from 0 to 9.

Examples

Input

00042

Output

42

Explanation

The five-character string 00042 represents integer 4242. Its three leading zeroes do not change the numeric value. int("00042") yields 4242, so the program prints 42.
