A number is perfect if the sum of its proper divisors (i.e., divisors excluding the number itself) is equal to itself. For example, 28 is perfect because 1+2+4+7+14 = 28. Cody Problems 1012, 2544, and 47458 deal with the perfect numbers.
If the sum of proper divisors is less than the number, it is called deficient, and if it is greater than the number, it is abundant. For example, 21 is deficient (1+3+7 = 11 < 21) and 24 is abundant (1+2+3+4+6+8+12 = 36).
Write a function to classify numbers as abundant, deficient, or perfect.
