Solution: Minimum Number of K Consecutive Bit Flips

Explore how to determine the minimum flips needed to convert a binary array to all ones by flipping k consecutive bits at a time. Learn a step-by-step approach involving tracking flip states with a queue, ensuring efficiency with O(n) time complexity and O(k) space complexity. This lesson helps you understand the algorithm's logic for solving bitwise problems and its implementation details in Go.

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 $1$ . However, we can only flip k consecutive bits at a time. So, for a binary array $[1, 1, 0, 0]$ and k = $2$ , we can flip the last two bits to get $[1, 1, 1, 1]$ . This means we only need a single k flip to turn the entire array into all $1$ s.

If nums cannot be converted to an array with all ...
