LeetCode ProblemMinimum Operations to Make Binary Array Elements Equal to One I
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.
