Valid Triangle Check

Write a program that checks if three sides can form a valid triangle. The sides are provided as positive integers. Print 'YES' if they can form a triangle, otherwise print 'NO'. ### Input Format: Three positive integers a, b, c (1 <= a, b, c <= 10^6). ### Output Format: A single string either 'YES' or 'NO'. ### Example: Input: 3 4 5 Output: YES ### Explanation: The triangle inequality states that for any triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
