Description

Given three positive integers representing the lengths of three line segments, determine whether these three segments can form a triangle.
If they can form a triangle, output "yes"; otherwise, output "no".
Hint: In a triangle, the sum of any two sides must be greater than the third side, and the difference of any two sides must be less than the third side.

Input Format

The input consists of a single line containing three positive integers, representing the lengths of the three line segments. The numbers are separated by a single space.

Output Format

If the segments can form a triangle, output "yes"; otherwise, output "no".
