A semiperfect number, also known as a weakly perfect number, is a type of integer that can be defined in the context of its divisors. Specifically, a positive integer \\( n \\) is considered semiperfect if the sum of some of its divisors (excluding the number itself) is equal to \\( n \\). For example, consider the number 12.
