Solution: Maximum Width Ramp
Explore a stack-based solution to determine the maximum width ramp in an integer array. Understand how maintaining a decreasing stack of indices allows efficient identification of valid ramps. This lesson helps you implement a linear time and space algorithm by scanning the array twice to compute the maximum width ramp.

Statement
A ramp in an integer array nums is defined as a pair of indices (i, j) such that i < j and nums[i] <= nums[j]. The width of such a ramp is j - i.
Given an integer array nums, find and return the maximum width of any ramp in nums. If no valid ramp exists, return
