Solution: Minimum Number of K Consecutive Bit Flips

Explore how to solve the problem of flipping k consecutive bits in a binary array to convert all bits to 1s with the minimum number of flips. Understand the use of a deque for tracking flips, managing flip states, and handling edge cases within O(n) time complexity for efficient bitwise manipulation tasks.

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 $1$ . 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 ...
