Implement FreqStack, a class which simulates the operation of a stack-like data structure. FreqStack has two functions: push(int x), which pushes an integer x onto the stack. pop(), which removes and returns the most frequent element in the stack. If…

题目链接:https://leetcode.com/problems/maximum-frequency-stack/ 题意:实现一种数据结构FreqStack,FreqStack需要实现两个功能: push(int x) : 将x放入栈中 pop(): 移除并返回栈中出现次数最多的元素,若果该元素不唯一,返回离栈顶最近的 思路:维护一个set,set中存储元素值,以及一个包含该元素在原栈中的出现次序的栈,排序先按照set中栈的大小排序,栈大小相同则按照栈顶元素大小排序.push若该元素不在se…

写了段jq后,报这个错,度娘未解,灵光一闪,找到原因,上代码: Html 结构: <a href="javascript:;" class="item-pic"> <p class="tit">封面</p> <input type="file" name="file" style="width:50px;height:50px;display:none&q…

在用使用Ext.encode(ExtObject)过程中抛出了如下错误: Uncaught RangeError: Maximum call stack size exceeded 实际上,不能用 Ext.encode 处理 Ext对象(比如Ext.Store),这是一个bug.当然,用该方法处理其他JSON时不会出现异常.…
