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

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
