【Java数据结构】栈与队列经典面试题——刷题笔记（下）

4. 用栈实现队列题目：思路：队列是先进先出，需要用到两个栈才能实现队列指定S1为输入栈，S2为输出栈入队时，直接将元素压入S1栈即可出队时，要将输入栈S1中的元素依次出栈，并压入输出栈S2中，然后将S2栈顶元素出栈，这样就能实现先入队的元素先出队，有一点要...

【Java数据结构】栈与队列经典面试题——刷题笔记（上）

1. 实现一个最小栈题目：思路：把题目要求的最小栈内部分为两个栈，一个stack用于储存所有元素，另一个min_stack用于储存最小的元素压入第一个元素时，这个元素就是当前栈里最小元素，所以不光要压入stack栈中也要压入min_stack栈中压入第二个元素的时候，要判断这个元素是否小于min_s...
