А+B=С?
Petya is bored with solving simple problems where you need to find the sum of two numbers, so his programming teacher gave a difficult problem that sounds like this:
Given three integers a, b and c. Determine whether is there such a number among them that equals the sum of two other numbers.
Input data
First line contains three integers a, b and c~(0 \le a, b, c \le 100).
Output data
Print "Yes", if such number exists. Otherwise print "No".
