Given two integer arrays nums1 and nums2, return the maximum length of a subarray that appears in both arrays. A subarray is a contiguous portion of an array.
Two integer arrays nums1 and nums2.
An integer representing the maximum length of the repeated subarray.
1 <= nums1.length, nums2.length <= 1000 0 <= nums1[i], nums2[i] <= 100
Example 1
Input
nums1 = [1,2,3,2,1], nums2 = [3,2,1,4,7]
Output
3
Explanation
The longest common subarray is [3,2,1].
Example 2
Input
nums1 = [0,0,0,0,0], nums2 = [0,0,0,0,0]
Output
5
Explanation
The entire array is common.
