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.

s = "  2    3  "
fields = s.split
for i in range(fields.len-1, 0)
    if fields[i] == "" then fields.remove i
end for
if fields.len < 2 then
    print "Not enough input"
else
    print val(fields[0]) + val(fields[1])
