Background

This is a classic introductory problem designed to help users get familiar with the Online Judge (OJ) registration and submission process. It is also commonly used by administrators for OJ server stress testing.

Welcome to the world of programming! Successfully solving this problem means you’ve mastered the most basic programming task: the “$1 + 1$” problem. Of course, this problem isn’t actually about calculating $1 + 1$ — instead, you’ll need to compute the sum of $A + B$.

Description

You are given two integers, $A$ and $B$. Write a program to automatically calculate and output their sum.

I/O Format

Input Format

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

All inputs are guaranteed to be within the $\texttt{int}$ range.

Output Format

Output a single line containing one integer — the sum of $A$ and $B$.

I/O Example

Hint

Be aware that adding two $\texttt{int}$ values may result in a sum that exceeds the $\texttt{int}$ range.
