Given the pseudocode

Question

procedure thing(a_1,a_2,a_3,...a_n:integers)

sum1 := 0

sum2 := 0

for i := 1 to n

if (a_i > 0), sum1 := sum1 + a_i

if (a_i < 0), sum2 := sum2 + a_i

end-for

return(sum1,sum2)

For the set of values {1,5,-2,-9,2,5,-7} as input for the above algorithm, what are the values of sum1 and sum2 that will be returned?

Answer 1

The sum of the positive integers is 13

The sum of the negative integers is -18
