Advanced Example 10 Devise a program to receive a positive number, and print all prime numbers less than or equal to that number We are going to reuse our solution to Advanced Example 4 (to check if a number is prime or not). we need to modify it a bit to return a True or False answer though. York University EECS 1012F2023 ...continued This is called sub-algorithm A sub-algorithm is called from other algorithms We called the prime sub- algorithm from inside our AE10 When tracing an algorithm, we normally treat sub-algorithms as a black box (and we assume they are correct) precondition: num = N postcondition: output all prime numbers ≤ num Exercise: trace advanced example 10, for when input is 8 York University EECS 1012 F2023 14-2 start num 1<--1+1 prime(/) = true T end is num Comp.
