Solution: Minimum Number of K Consecutive Bit Flips

Explore how to determine the minimum number of flips required to convert a binary array to all ones by flipping k consecutive bits at a time. Understand the use of tracking mechanisms and pointers to optimize the flipping process, ensuring efficient problem-solving with O(n) time complexity and O(k) space complexity.

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 ...
