Given three natural numbers A, B, and C, a triangle with these sides can exist only if it satisfies these conditions:
1. A + B > C
2. A + C > B
3. B + C > ABasically, a triangle is valid only if the sum of its two sides is greater than the third side.
Write a program that takes three integer inputs and evaluates if the triangle exists. If a triangle can be constructed using the three numbers, then output the "YES" string; otherwise, output "NO".
