Contiguous Array
Given a binary array nums, return the maximum length of a contiguous subarray with an equal number of 0 and 1.
Example 1
Input
nums = [0,1]Output
2[0, 1] is the longest contiguous subarray with an equal number of 0 and 1.
Example 2
Input
nums = [0,1,0]Output
2[0, 1] (or [1, 0]) is a longest contiguous subarray with equal number of 0 and 1.
Constraints
- 1 <= nums.length <= 10^5
- nums[i] is either 0 or 1.
