2535 - Difference Between Element Sum and Digit Sum of an Array.<p>Easy</p> <p>You are given a positive integer array <code>nums</code>.</p> <ul> <li>The <strong>element sum</strong> is the sum of all the elements in <code>nums</code>.</li> <li>The <strong>digit sum</strong> is the sum of all the digits (not necessarily distinct) that appear in <code>nums</code>.</li> </ul> <p>Return <em>the <strong>absolute</strong> difference between the <strong>element sum</strong> and <strong>digit sum</strong> of</em> <code>nums</code>.</p> <p><strong>Note</strong> that the absolute difference between two integers <code>x</code> and <code>y</code> is defined as <code>|x - y|</code>.</p> <p><strong>Example 1:</strong></p> <p><strong>Input:</strong> nums = [1,15,6,3]</p> <p><strong>Output:</strong> 9</p> <p><strong>Explanation:</strong></p> <p>The element sum of nums is 1 + 15 + 6 + 3 = 25.</p> <p>The digit sum of nums is 1 + 1 + 5 + 6 + 3 = 16.</p> <p>The absolute difference between the element sum and digit sum is |25 - 16| = 9.</p> <p><strong>Example 2:</strong></p> <p><strong>Input:</strong> nums = [1,2,3,4]</p> <p><strong>Output:</strong> 0</p> <p><strong>Explanation:</strong></p> <p>The element sum of nums is 1 + 2 + 3 + 4 = 10.</p> <p>The digit sum of nums is 1 + 2 + 3 + 4 = 10.</p> <p>The absolute difference between the element sum and digit sum is |10 - 10| = 0.</p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= nums.length <= 2000</code></li> <li><code>1 <= nums[i] <= 2000</code></li> </ul>
