+3736\. Minimum Moves to Equal Array Elements III
+
+Easy
+
+You are given an integer array `nums`.
+
+In one move, you may **increase** the value of any single element `nums[i]` by 1.
+
+Return the **minimum total** number of **moves** required so that all elements in `nums` become **equal**.
+
+**Example 1:**
+
+**Input:** nums = [2,1,3]
+
+**Output:** 3
+
+**Explanation:**
+
+To make all elements equal:
+
+*   Increase `nums[0] = 2` by 1 to make it 3.
+*   Increase `nums[1] = 1` by 1 to make it 2.
+*   Increase `nums[1] = 2` by 1 to make it 3.
+
+Now, all elements of `nums` are equal to 3. The minimum total moves is `3`.
+
+**Example 2:**
+
+**Input:** nums = [4,4,5]
+
+**Output:** 2
+
+**Explanation:**
+
+To make all elements equal:
+
+*   Increase `nums[0] = 4` by 1 to make it 5.
+*   Increase `nums[1] = 4` by 1 to make it 5.
+
+Now, all elements of `nums` are equal to 5. The minimum total moves is `2`.
+
+**Constraints:**
+
+*   `1 <= nums.length <= 100`
+*   `1 <= nums[i] <= 100`
