Solution: Maximum Width Ramp
Explore how to solve the maximum width ramp problem by applying a stack-based greedy approach. Learn to maintain a monotonically decreasing stack to identify candidate left endpoints, then scan from right to left to find the widest ramp efficiently. This lesson helps you implement a linear time solution and understand the underlying algorithmic intuition.

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
