Checks all numbers to see if they are perfect, then prints the ones that are, then does the same for abundant and deficient numbers.

Explanation:
```
                  # Implicit input 'n'
'   ;,            # Print any numbers in [1..n] for which the following is true:
 ∆K=              #   The number = the sum of its proper divisors
      '   ;,      # Print any numbers in [1..n] for which the following is true:
       ∆K<        #   The number < the sum of its proper divisors
            '     # Push a list of numbers in [1..n] for which the following is true:
             ∆K>  #   The number > the sum of its proper divisors
                  # 'o' flag - Implicit output regardless of having printed
