Leetcode 716. Max Stack
Reported Feb 6, 2026 · 3 source reports

View sourceRead this source's wording
Design a stack that supports push, pop, top, peekMax, and popMax (which removes the most recently added maximum element if there are duplicates). The challenge is to maintain fast retrieval and removal of the current maximum even when it isn't at the top, so choose data structures that allow efficient max lookup and deletion.
