Cody Problems 1933 and 46898 deal with 
, the sum of divisors function. This problem deals with 
, the sum of unitary divisors functions. Unitary divisors are defined in Cody Problem 56738, which asks for a list of the unitary divisors of a number, and they appear in Cody Problem 56743, which asks for a count.
, the sum of divisors function. This problem deals with , the sum of unitary divisors functions. Unitary divisors are defined in Cody Problem 56738, which asks for a list of the unitary divisors of a number, and they appear in Cody Problem 56743, which asks for a count. Write a function to sum the unitary divisors of a number. For example, the unitary divisors of 18 are 1, 2, 9, and 18; therefore, the sum is 30.
