1390\. Four Divisors

Medium

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
