You are given a non-negative integer array nums. In one operation, you must:
- Choose a positive integer
xsuch thatxis less than or equal to the smallest non-zero element innums. - Subtract
xfrom every positive element innums.
Return the minimum number of operations to make every element in nums equal to 0.
1Example 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]2Example 2
Input
nums = [0]
Output
0
Explanation
Each element in
nums is already 0 so no operations are needed.Constraints
Limits and guarantees your solution can rely on.
1 <= nums.length <= 1000 <= nums[i] <= 100
