1558 - Minimum Numbers of Function Calls to Make Target Array\. Medium You are given an integer array `nums`. You have an integer array `arr` of the same length with all values set to `0` initially. You also have the following `modify` function: ![](https://assets.leetcode.com/uploads/2020/07/10/sample_2_1887.png) You want to use the modify function to covert `arr` to `nums` using the minimum number of calls. Return _the minimum number of function calls to make_ `nums` _from_ `arr`. The test cases are generated so that the answer fits in a **32-bit** signed integer. **Example 1:** **Input:** nums = [1,5] **Output:** 5 **Explanation:** Increment by 1 (second element): [0, 0] to get [0, 1] (1 operation). Double all the elements: [0, 1] -> [0, 2] -> [0, 4] (2 operations). Increment by 1 (both elements) [0, 4] -> [1, 4] -> **[1, 5]** (2 operations). Total of operations: 1 + 2 + 2 = 5. **Example 2:** **Input:** nums = [2,2] **Output:** 3 **Explanation:** Increment by 1 (both elements) [0, 0] -> [0, 1] -> [1, 1] (2 operations). Double all the elements: [1, 1] -> **[2, 2]** (1 operation). Total of operations: 2 + 1 = 3. **Example 3:** **Input:** nums = [4,2,5] **Output:** 6 **Explanation:** (initial)[0,0,0] -> [1,0,0] -> [1,0,1] -> [2,0,2] -> [2,1,2] -> [4,2,4] -> **[4,2,5]**(nums). **Constraints:** * 1 <= nums.length <= 105 * 0 <= nums[i] <= 109
