Solution: Minimum Number of K Consecutive Bit Flips

Explore how to determine the minimum number of k consecutive bit flips needed to turn a binary array into all ones. Understand the tracking of flip states using a deque, conditions for flipping, and how to handle cases where conversion is not possible. This lesson covers an O(n) solution with O(k) space complexity, enhancing problem-solving skills with bitwise manipulation.

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 ...
