Use of Multi-Language (Coding): Perfect Numbers Test

The problem requires checking whether a given number N is a perfect number or not. A number is considered perfect if the sum of its proper divisors (factors excluding itself) is equal to the number itself. For example, 6 is a perfect number as its factors are 1, 2, 3, and 6, and 1+2+3=6. The solution involves iterating through all the factors of the given number and computing their sum, then comparing it with the original number to determine if it is perfect or not. If the sum of factors is equal to N, then N is a perfect number, otherwise, it is not.
