Minimum Number of K Consecutive Bit Flips

Explore solving the problem of flipping k consecutive bits in a binary array to make all bits equal to one. Learn how to determine the minimum number of flips required, or identify when it is impossible. This lesson builds your skills in bitwise manipulation and problem-solving strategies for coding interviews.

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 [1,1,0,0][1, 1, 0, 0] ...
