You are given two 0-indexed integer arrays nums1 and nums2 of length n.
Let's define another 0-indexed integer array, nums3, of length n. For each index i in the range [0, n - 1], you can assign either nums1[i] or nums2[i] to nums3[i].
Your task is to maximize the length of the longest non-decreasing subarray in nums3 by choosing its values optimally.
Return an integer representing the length of the longest non-decreasing subarray in nums3.
Note: A subarray is a contiguous non-empty sequence of elements within an array.

Example 1:
\n\n\nInput: nums1 = [2,3,1], nums2 = [1,2,1]\nOutput: 2\nExplanation: One way to construct nums3 is: \nnums3 = [nums1[0], nums2[1], nums2[2]] => [2,2,1]. \nThe subarray starting from index 0 and ending at index 1, [2,2], forms a non-decreasing subarray of length 2. \nWe can show that 2 is the maximum achievable length.\n\n
Example 2:
\n\n\nInput: nums1 = [1,3,2,1], nums2 = [2,2,3,4]\nOutput: 4\nExplanation: One way to construct nums3 is: \nnums3 = [nums1[0], nums2[1], nums2[2], nums2[3]] => [1,2,3,4]. \nThe entire array forms a non-decreasing subarray of length 4, making it the maximum achievable length.\n\n\n
Example 3:
\n\n\nInput: nums1 = [1,1], nums2 = [2,2]\nOutput: 2\nExplanation: One way to construct nums3 is: \nnums3 = [nums1[0], nums1[1]] => [1,1]. \nThe entire array forms a non-decreasing subarray of length 2, making it the maximum achievable length.\n\n\n
