[LeetCode] 716. Max Stack

Design a max stack data structure that supports the stack operations and supports finding the stack's maximum element. Implement the MaxStack class: MaxStack() Initializes the stack object. void push(int x) Pushes element x onto the stack. int pop()

栈放入具体问题

1.栈与回文 package 数据结构; import java.util.Scanner; /** * * */ public class ArrayStack { private int maxStack; private int[] stack; private int top = -1; public ArrayStack(int maxStack) { this.maxStack = maxStack; this.stack = new int[th

数组模拟栈，实现简单回文判断

一、模拟栈 public class ArrayStack { /** * 栈的大小 */ private int maxStack; /** * 数组用来模拟栈 */ private int[] stack; /** * 表示栈顶所在的位置，默认情况下没有数据时，是-1 */ private int top = -1;
