Trace the following flowchart for when input is 28 and complete the trace table. Also, write pre- post-conditions for this flowchart. Assume input is a positive integer. The algorithm then checks if the number is equal to the sum of all its positive divisors (including 1 and excluding itself). It then output "Yes" "No" accordingly.

Trace the following flowchart for when input is 28 and complete the trace table. Also, write pre-
post-conditions for this flowchart. Assume input is a positive integer. The algorithm then checks if
the number is equal to the sum of all its positive divisors (including 1 and excluding itself). It then
output "Yes" "No" accordingly.
