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.



Example

INTEGER PROC FNMathGetSumAPlusBI( INTEGER A, INTEGER B )
 RETURN( A + B )

//
PROC Main()
 STRING s1[255] = "3"
 STRING s2[255] = "2"
 IF ( NOT ( Ask( "math: get: sum: a: plus: a (choose a number between -1000 and 1000) = ", s1, _EDIT_HISTORY_ ) ) AND ( Length( s1 ) > 0 ) ) RETURN() ENDIF
 IF ( NOT ( Ask( "math: get: sum: a: plus: b (choose a number between -1000 and 1000) = ", s2, _EDIT_HISTORY_ ) ) AND ( Length( s2 ) > 0 ) ) RETURN() ENDIF
 Message( FNMathGetSumAPlusBI( Val( s1 ), Val( s2 ) ) ) // gives e.g. 5
END
