Minimum Operations to Make Binary Array Elements Equal to One I
You are given a binary array nums.
You are given a binary array nums.
You can do the following operation on the array any number of times (possibly zero):
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. If it is impossible, return -1.
Example 1
Input: nums = [0,1,1,1,0,0]
Output: 3
Explanation: We can do the following operations:
Example 2
Input: nums = [0,1,1,1]
Output: -1
Explanation: It is impossible to make all elements equal to 1.
Constraints
- 3 <= nums.length <= 10^5
- 0 <= nums[i] <= 1
