// 2357. Make Array Zero by Subtracting Equal Amounts

// You are given a non-negative integer array nums. In one operation, you must:

// Choose a positive integer x such that x is less than or equal to the smallest non-zero element in nums.
// Subtract x from every positive element in nums.
// Return the minimum number of operations to make every element in nums equal to 0.

 

// Example 1:

// Input: nums = [1,5,0,3,5]
// Output: 3
// Explanation:
// In the first operation, choose x = 1. Now, nums = [0,4,0,2,4].
// In the second operation, choose x = 2. Now, nums = [0,2,0,0,2].
// In the third operation, choose x = 2. Now, nums = [0,0,0,0,0].
// Example 2:

// Input: nums = [0]
// Output: 0
// Explanation: Each element in nums is already 0 so no operations are needed.

    nums.sort((a,b) => a-b);

        for(let j = 0; j < nums.length; j++){
            nums[j] -= subtract
