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, return0
.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
