Leetcode Problem 487. Max Consecutive Ones II

487. Max Consecutive Ones II

Leetcode Solutions

Sliding Window Approach

  1. Initialize two pointers, left and right, to the start of the array.
  2. Initialize a variable max_consecutive to keep track of the maximum number of consecutive 1s found.
  3. Initialize a variable zero_count to keep track of the number of zeros in the current window.
  4. Iterate over the array with the right pointer, expanding the window to the right.
  5. When encountering a 0, increment zero_count.
  6. If zero_count exceeds 1, contract the window from the left until zero_count is 1 or less.
  7. Update max_consecutive with the maximum length of the window seen so far.
  8. Return max_consecutive as the result.
