2357 - Make Array Zero by Subtracting Equal Amounts.

Easy

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.

Constraints:

• 1 <= nums.length <= 100

• 0 <= nums[i] <= 100
