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



Task

Given two integers,   A and B.

Their sum needs to be calculated.



Input data

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

 



(
−
1000
≤
A
,
B
≤
+
1000
)


{\displaystyle (-1000\leq A,B\leq +1000)}




Output data

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

var line = console.input();
var nums = line.match(/^\s*([+-]?[0-9]+)\s+([+-]?[0-9]+)\s*/);
if (nums) {
    var A = Number(nums[1]);
    var B = Number(nums[2]);
    if (A <= 1000 && A >= -1000 && B <= 1000 && B >= -1000) {
        printf("%d\n", A + B);
    } else {
        puts("error: A and B both need to be in range -1000 thru 1000 inclusive");
    }
} else {
    puts("error: A+B requires two numbers separated by space");
