<p>Given an integer array <code>nums</code>, return <em>the sum of divisors of the integers in that array that have exactly four divisors</em>. If there is no such integer in the array, return <code>0</code>.</p> <p> </p> <p><strong>Example 1:</strong></p> <pre> <strong>Input:</strong> nums = [21,4,7] <strong>Output:</strong> 32 <strong>Explanation:</strong> 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. </pre> <p><strong>Example 2:</strong></p> <pre> <strong>Input:</strong> nums = [21,21] <strong>Output:</strong> 64 </pre> <p><strong>Example 3:</strong></p> <pre> <strong>Input:</strong> nums = [1,2,3,4,5] <strong>Output:</strong> 0 </pre> <p> </p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= nums.length <= 10<sup>4</sup></code></li> <li><code>1 <= nums[i] <= 10<sup>5</sup></code></li> </ul>
