Solution: Minimum Number of K Consecutive Bit Flips

Understand how to compute the minimum number of k-length consecutive bit flips needed to turn a binary array into all 1s. This lesson guides you through tracking flips efficiently and handling edge cases using a queue, optimizing time and space complexity to solve the problem in O(n) time.

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 ...
