A perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself. For instance, 6 has divisors 1, 2 and 3 (excluding itself), and 1 + 2 + 3 = 6, so 6 is a perfect number. See this website for more details.
In either C++, Java, C#, or Python, develop a program that performs the following functionality:
1) Create a function that does the hard work of determining "perfect number-ness"
- The one input parameter is an integer value which is the number value to test (Let's call it n)
- Sum up all the divisors of the number from 1 to n-1 (Let's call it sum)
- Return a boolean flag which indicates if the sum is equal to the test number (n equals sum)
2) In the main function, print all the perfect numbers from 1 to 10000
- Create a loop that iterates from values 1 to 10000
- For each iteration, call the function and use its result accordingly
- No user input is required or allowed
- 6, 28, 496, and 8128 are the only four values which are perfect numbers
