A perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself. A divisor of an integer x is an integer that can divide x evenly. Take an integer n as input from the keyboard, print true if n is a perfect number, otherwise, print false. You do not need to print any explanation, just print true or false. Use a for loop to generate the divisors. Example 1: Input: num = 28 Output: true Explanation: 28 = 1 + 2 + 4 + 7 + 14 1, 2, 4, 7, and 14 are all divisors of 28.   Example 2: Input: num = 6 Output: true   Example 3: Input: num = 496 Output: true         Example 4: Input: num = 8128 Output: true   Example 5: Input: num = 2 Output: false
