Sum of Two Integers

Given two integers A and B, compute their sum S defined by the formula:

\( S = A + B \)

Your task is to write a program that reads the two integers from the input and outputs their sum.

inputFormat

The input consists of a single line containing two space-separated integers, A and B.

Constraints: The integers can be positive, negative, or zero and will fit into a standard 32-bit signed integer.

outputFormat
