Introduction

This is an introductory problem to make sure you know how the submissions work. The problem is to take two integers and add them together.

Sum of Two Digits

Compute the sum of two single-digit numbers.

  • Input: Two single-digit numbers.
  • Output: The sum of these numbers.
  Description
Input Format Integers a and b on the same line separated by a space.
Output Format The sum of a and b.
Constraints \(0 \le a,b \le 9\)

Input

Output 

16

Setup

In order for the grader to know what interpreter you're using you have to put a comment at the top of the file. 

# Uses python 3

In addition, the inputs are given via stdin so you need to import sys to read it. 

import sys

The Input

So the first thing to do is read in the inputs. Since standard input is a string we need to split it to get the two terms and then cast them to integers. I'm assuming the grader behaves well and so I'm not doing any kind of checking of the input. 

a, b = sys.stdin.read().split()
a, b = int(a), int(b)

The Solution

In order to give the grader my output I have to print it. 

print(a + b)
