You are given two non-increasing 0-indexed integer arrays nums1​​​​​​ and nums2​​​​​​.

\n\n

A pair of indices (i, j), where 0 <= i < nums1.length and 0 <= j < nums2.length, is valid if both i <= j and nums1[i] <= nums2[j]. The distance of the pair is j - i​​​​.

\n\n

Return the maximum distance of any valid pair (i, j). If there are no valid pairs, return 0.

\n\n

An array arr is non-increasing if arr[i-1] >= arr[i] for every 1 <= i < arr.length.

Example 1:

\n\n
\nInput: nums1 = [55,30,5,4,2], nums2 = [100,20,10,10,5]\nOutput: 2\nExplanation: The valid pairs are (0,0), (2,2), (2,3), (2,4), (3,3), (3,4), and (4,4).\nThe maximum distance is 2 with pair (2,4).\n
\n\n

Example 2:

\n\n
\nInput: nums1 = [2,2,2], nums2 = [10,10,1]\nOutput: 1\nExplanation: The valid pairs are (0,0), (0,1), and (1,1).\nThe maximum distance is 1 with pair (0,1).\n
\n\n

Example 3:

\n\n
\nInput: nums1 = [30,29,19,5], nums2 = [25,25,25,25,25]\nOutput: 2\nExplanation: The valid pairs are (2,2), (2,3), (2,4), (3,3), and (3,4).\nThe maximum distance is 2 with pair (2,4).\n
