Minimum Operations to Make Binary Array Elements Equal to One II
You are given a binary array nums.
You can do the following operation on the array any number of times (possibly zero):
- Choose any index
ifrom the array and flip all the elements from indexito the end of the array.
Flipping an element means changing its value from 0 to 1, and from 1 to 0.
Return the minimum number of operations required to make all elements in nums equal to 1.
Example 1
Input
nums = [0,1,1,0,1]Output
4By choosing indices 1, 0, 4, and 3 in order, all elements become 1 after 4 operations.
Example 2
Input
nums = [1,0,0,0]Output
1Choosing index 1 flips the suffix [0,0,0] to [1,1,1], making all elements equal to 1 in one operation.
Constraints
- 1 <= nums.length <= 10^5
- 0 <= nums[i] <= 1
