You are given an integer array nums containing distinct numbers, and you can perform the following operations until the array is empty:
Return an integer denoting the number of operations it takes to make nums empty.
Example 1:
Input: nums = [3,4,-1] Output: 5
| Operation | Array | 
|---|---|
| 1 | [4, -1, 3] | 
| 2 | [-1, 3, 4] | 
| 3 | [3, 4] | 
| 4 | [4] | 
| 5 | [] | 
Example 2:
Input: nums = [1,2,4,3] Output: 5
| Operation | Array | 
|---|---|
| 1 | [2, 4, 3] | 
| 2 | [4, 3] | 
| 3 | [3, 4] | 
| 4 | [4] | 
| 5 | [] | 
Example 3:
Input: nums = [1,2,3] Output: 3
| Operation | Array | 
|---|---|
| 1 | [2, 3] | 
| 2 | [3] | 
| 3 | [] | 
Constraints:
1 <= nums.length <= 105-109 <= nums[i] <= 109nums are distinct.
