Implement a stack with min () function, which'll return the smallest number in the stack.It should support push, POPs and min operation all in O (1) cost.NoticeMin operation'll never be called if there are no number in the stack.Has you met this question in a real interview?YesExamplepush(1)pop() // return 1push(2)push(3)min() // return 2push(1)min() // return 1For the original question on Leetcode, please see my previous blog min Stack.Solution One:classMinstack { Public: Minstack () {}vo
that Map does not inherit the Collection interface. Map provides the key ing between key and value. A Map cannot contain the same key, and each key can only Map one value. The Map interface provides three sets of views. The Map content can be treated as a set of keys, a set of values, or a set of key-value ing.
Implementation classes of the Map interface include HashMap and TreeMap. HashMap: The thread is unsafe and efficient. The key or value is allowed to be null. HashTable: thread security a

JavaScript modular programming has become an urgent requirement. Ideally, developers only need to implement the core business logic, and others can load other people's written modules.However, JavaScript is not a modular programming language, and it does not support "classes", let alone "modules".The JavaScript community has made a lot of effort to implement the "m
