Understanding the Make Array Zero by Subtracting Equal Amounts Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
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.

How Interview Coder Helps
Get real-time assistance for Make Array Zero by Subtracting Equal Amounts problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
nums = [1,5,0,3,5]
3
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].
nums = [0]
0
Each element in nums is already 0 so no operations are needed.
Constraints
1 <= nums.length <= 100
0 <= nums[i] <= 100
