Solution: Longest Subarray of 1's After Deleting One Element

Explore how to apply the sliding window technique to solve the problem of finding the longest subarray consisting entirely of 1s after deleting exactly one element from a binary array. Understand the use of two pointers to maintain a window with at most one zero, ensuring efficient computation with linear time complexity and constant space. This lesson helps you develop a clear strategy to manipulate array windows and optimize subarray searches in coding interviews.

Statement

Given a binary array nums, remove exactly one element from it. Return the length of the longest non-empty subarray consisting entirely of 11's in the resulting array. If no such subarray exists, return 00.

Note: Exactly one element must always be deleted, even if all elements are 11's.

Constraints:

  • 11 \leq nums.length 105\leq 10^5 ...
