Longest Subarray of 1's After Deleting One Element

Medium

Provided a binary array nums, you should delete one element from it.

Produce the size of the longest non-empty subarray containing only 1's in the resulting array. Produce 0 if there is no such subarray.

Example 1

Input: nums = [1,1,0,1]

Output: 3

Explanation: After deleting the number in position 2, [1,1,1] has 3 numbers with value of 1's.

Example 2

Input: nums = [0,1,1,1,0,1,1,0,1]

Output: 5

Explanation: After deleting the number in position 4, [0,1,1,1,1,1,0,1] longest subarray with value of 1's is [1,1,1,1,1].

Example 3

Input: nums = [1,1,1]

Output: 2

Explanation: You must delete one element.

Constraints

  • 1 <= nums.length <= 10^5
  • nums[i] is either 0 or 1.
