Solution: Minimum Number of K Consecutive Bit Flips

Explore how to determine the minimum number of k consecutive bit flips needed to convert a binary array into all ones. Learn to track flipping states, apply deque for efficient state management, and handle edge cases. This lesson provides a clear step-by-step approach and code implementation to master this bitwise manipulation problem.

We'll cover the following...

Statement

We are given a binary arrayAn array consisting of 0s and 1s only. nums and an integer k. Our task is to find the minimum number of flipsChanging a 0 to a 1 or a 1 to a 0. needed to make all the bits in the array equal to 11. However, we can only flip k consecutive bits at a time. So, for a binary array [1,1,0 ...
