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 a, b as integer
 
  a = strVals(0).toInteger
  b = strVals(1).toInteger
 
  if a < -1000 or b > 1000 then
    print("The first number should be greater than or equal to -1000 and the second number should be less " + _
    "than or equal to 1000. Please re-enter:")
    continue
  end
 
  var result as integer = a + b
