Question

In the pseudocode below:

Function Integer perfect(Integer n)
        Declare Integer count = 0
        Declare Integer sum = 0

        While count < n
                Set count = count + 1
                Set sum = sum + count
        End While

        Return sum
End Function

Function Integer perfect_sum(Integer n)
        Declare Integer count = 0
        Declare Integer sum = 0

        While count < n
                Set count = count + 1
                Set sum = sum + perfect(count)
        End While

        Return sum
End Function    

Module main()
        Display perfect_sum(5)
End Module

What will be the output when the main module is called (separate each output with a single space)?

Answer 1

Output:
--------
35

Explanation:
----------------
perfect(1) is 1
perfect(2) is 1+2 = 3
perfect(3) is 1+2+3 = 6
perfect(4) is 1+2+3+4 = 10
perfect(5) is 1+2+3+4+5 = 15

so, perfect_sum(5) = 1+3+6+10+15 = 35
