Maximum Consecutive Ones Problem Statement

Given a binary array 'ARR' of size 'N', your task is to determine the maximum length of a sequence consisting solely of 1’s that can be obtained by converting at most 'K' zeroes into ones.

Example:

Input:

For example, if there are 2 test cases: TestCase 1: N = 6, ARR = [1, 1, 0, 0, 1, 1], K = 1 TestCase 2: N = 9, ARR = [1, 0, 1, 0, 1, 0, 1, 1, 1], K = 2

Output:

For TestCase 1, the output is 4.
For TestCase 2, the output is 7.

Explanation:

For TestCase 1: By flipping the third or fourth zero, we can have a maximum sequence of four 1's.
For TestCase 2: By flipping the second and fourth zeroes, we achieve a sequence of seven 1's.

Constraints:

1 ≤ T ≤ 10

1 ≤ N ≤ 5 * 10⁴

0 ≤ Arr[i] ≤ 1

0 ≤ K ≤ N

Note:

You do not need to print anything, it has already been taken care of. Just implement the given function.

Accepted Answer

The task is to find the maximum length of a sequence of 1's by converting at most K zeroes into ones in a binary array.

Iterate through the array and keep track of the current window of 1's and zeroes.
Use a sliding window approach to find the maximum length of consecutive 1's by flipping at most K zeroes.
Update the window based on the number of zeroes flipped and keep track of the maximum length found so far.
Return the maximum length of consecutive 1's obtained.
