Understanding the Minimum Operations to Make Binary Array Elements Equal to One I I Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
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 i from the array and flip all the elements from index i to 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.

Examples
nums = [0,1,1,0,1]
4
We can do the following operations: Choose the index i = 1. The resulting array will be nums = [0,0,0,1,0]. Choose the index i = 0. The resulting array will be nums = [1,1,1,0,1]. Choose the index i = 4. The resulting array will be nums = [1,1,1,0,0]. Choose the index i = 3. The resulting array will be nums = [1,1,1,1,1].
nums = [1,0,0,0]
1
We can do the following operation: Choose the index i = 1. The resulting array will be nums = [1,1,1,1].
Constraints
1 <= nums.length <= 105
0 <= nums[i] <= 1
