Problem Description

Given three positive integers representing the lengths of three line segments, determine whether these three segments can form a triangle.

Input Format

The input consists of a single line containing three positive integers, each representing the length of a line segment, separated by a space. (The length of each side does not exceed $10000$.)

Output Format

If the segments can form a triangle, output 1; otherwise, output 0.
