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.
