Solution: Maximum Width Ramp
Explore how to use stacks to solve the Maximum Width Ramp problem by efficiently identifying valid index pairs and computing the largest width. This lesson teaches a greedy two-pass algorithm that scans and updates indices to find the optimal ramp with O(n) time complexity, helping you apply stack concepts to coding interviews.

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
