Given an integer array `nums`, return the sum of divisors of the integers in that array that have exactly four divisors. If there is no such integer in the array, return `0`.

Example 1:

    Input: nums = [21,4,7]
    Output: 32
    Explanation:
    21 has 4 divisors: 1, 3, 7, 21
    4 has 3 divisors: 1, 2, 4
    7 has 2 divisors: 1, 7
    The answer is the sum of divisors of 21 only.

Example 2:

    Input: nums = [21,21]
    Output: 64

Example 3:

    Input: nums = [1,2,3,4,5]
    Output: 0

Constraints:

- `1 <= nums.length <= 104`
- `1 <= nums[i] <= 105`
