A stack is an ordered collection of items for which we can only add or remove items from one end (the top of the stack). The stack is another container class, much like a list, but with a much more limited set of operations: push, pop and size . The proposed work presents a ...

Getting both the minimum and the maximum values in the stack at any given point in time. All class methods, when considered independently, should run in constant time and with constant space. // All operations below are performed sequentially.MinMaxStack():-// instantiate a MinMaxStackpush(5)...

: stack is First In Last Out while queue is First In First Out. stack1 used for push, stack2 used for pop. if we push a, b, c in stack1, when we pop, we push every element into stack2 for pop. when new element comes in, still use stack1 for push. when pop, if stack2…...

pop() -- Removes the element on top of the stack. top() -- Get the top element. getMin() -- Retrieve the minimum element in the stack. Example: MinStack minStack = new MinStack(); minStack.push(-2); minStack.push(0); minStack.push(-3); minStack.getMin(); --> Returns -...
队列的一个基本特点是,元素先进先出。通过两个栈来模拟时,首先我们将两个栈分为栈 1 和栈 2。当执行队列的 push 操作时,直接 将元素 push 进栈 1 中。当队列执行 pop 操作时,首先判断栈 2 是否为空,如果不为空则直接 pop 元素。如果栈 2 为空,则将栈 1 中 ...
