Leetcode 895. Maximum Frequency Stack
Design a stack-like data structure supporting push(val) and pop() where pop removes the most frequent element (breaking ties by recency, i.e., the one closest to the top). The core challenge is efficiently tracking element frequencies and their ordering so many operations (up to ~2×10^4) can be handled quickly.
