面试题 03.02.栈的最小值

1. 题目描述

请设计一个栈,除了常规栈支持的pop与push函数以外,还支持min函数,该函数返回栈元素中的最小值。执行push、pop和min操作的时间复杂度必须为O(1)。

示例:

MinStack minStack = new MinStack();
minStack.push(-2);
minStack.push(0);
minStack.push(-3);
minStack.getMin();   --> 返回 -3.
minStack.pop();
minStack.top();      --> 返回 0.
minStack.getMin();   --> 返回 -2.
