[题目] Design a stack that supports push, pop, top, and retrieving the minimum element in constant time. push(x) -- Push element x onto stack. pop() -- Removes the element on top of the stack. top() -- Get the top element. getMin() -- Retrieve the mini…
栈 一言以蔽之,就是后进的先出(LIFO). C语言实现代码: #include<stdio.h> #include<stdlib.h> typedef struct Stack { /*Stack has three properties.*/ int capacity; //the maximum number of elements stack can hold int size; //current size of stack int *elements; //array…
