A ramp in an integer array nums is a pair (i, j) for which i < j and nums[i] <= nums[j]. The width of such a ramp is j - i.
Given an integer array nums, return the maximum width of a ramp in nums. If there is no ramp in nums, return 0.
\n
Example 1:
\n\n\nInput: nums = [6,0,8,2,1,5]\nOutput: 4\nExplanation: The maximum width ramp is achieved at (i, j) = (1, 5): nums[1] = 0 and nums[5] = 5.\n\n\n
Example 2:
\n\n\nInput: nums = [9,8,1,0,1,9,4,0,4,1]\nOutput: 7\nExplanation: The maximum width ramp is achieved at (i, j) = (2, 9): nums[2] = 1 and nums[9] = 1.\n\n\n

Constraints:
\n\n2 <= nums.length <= 5 * 1040 <= nums[i] <= 5 * 104Compiled with clang 11 using the latest C++ 17 standard.
