Solution: Maximum Width Ramp

Explore the stack-based approach to solve the Maximum Width Ramp problem in an integer array. Learn how to build a decreasing stack of candidate left endpoints and scan from right to left to find the widest ramp efficiently. This lesson provides a step-by-step solution with time and space complexity analysis for optimal algorithm design in 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 00 ...
