Problem Statement

A+B   ─── a classic problem in programming contests,   it's given so contestants can gain familiarity with the online judging system being used.

Given two integers,   A and B. Their sum needs to be calculated.

Two integers are written in the input stream, separated by space(s):

The required output is one integer:   the sum of A and B.

Let's start with the solution:

MODULE  ab;

IMPORT  In, Out;

VAR     A, B    : INTEGER;

BEGIN
  In.Int (A);
  In.Int (B);
  Out.Int (A + B, 8);
  Out.Ln
END ab.
