Sum of Three Elements Array

Background

Congcong is currently learning programming and has encountered a very basic problem: calculating the sum of all elements in a fixed-length array. He hopes you can help him solve this problem.

Problem Description

Given an array of $3$ integers, return the sum of all its elements.

Input Format

Input is given from standard input in the following format.

A single line containing three integers $a, b, c$, separated by spaces.

Output Format

Output is printed to standard output in the following format.

Output a single integer, representing the sum of $a, b, c$.

Sample

1 2 3

6

5 11 2

18

7 0 0

7

Sample Explanation

For the first sample, the three input integers are $1, 2, 3$. Their sum is $1 + 2 + 3 = 6$.

Constraints

For all test cases: $-1000 \le a, b, c \le 1000$ Time limit: 1 second, Memory limit: 1024KB.
