Problem 2: The following pseudocode and flowchart have been designed to get an integer number from the user and print if it is a perfect number or not.

Note: a perfect number is a positive integer which is equal to the sum of its proper divisors, excluding itself. For example 6 and 28 are perfect numbers because 6 = 1+2+3 and 28=1,2,4,7,14.

1: Start

2: num = 0

3: sum = 1

4: divider = 2

5: Read (num)

6: While ((num / 2) >= divider) DO

7: IF (num % divider == 0) Then

8: sum=sum+ divider

9: End IF

10: divider = divider + 1

11: End While

12: IF (num == sum AND num != 1) Then

13: Print (num , is a perfect number.)

14: Else

15: Print (num , is not a perfect number.)

16: End IF

17: End

Problem 2: The following pseudocode and flowchart have been designed to get

i. Using a trace table (one per input), trace the algorithm for the following values and show the output. See the end of document for an example trace table using input 7. 25, 1, 0, 6, 28

ii. Modify the psuedocode or the flowchart in order to print out all the perfect numbers between a range of values given by the user, for example between 1 and 1000, or 200 and 800, etc

an integer number from the user and print if it is a
