set_map的实现+set/map加持秒杀高频算法题锻炼算法思维

set类的实现 set的声明：T就是set底层的关键字的类型；set默认要求支持T比较，如果不支持或者想按照自己的需求走可以自行实现仿函数传给第二个模板参数。set底层存储数据的内存是从空间配置器申请的，如果需要可以自己实现内存池，传给第三个参数。 set底层是红黑树实现，增删查效率是O（logN)...

Map和Set巧解力扣算法问题

前言问题一：什么是Map和Set？ES6以前，在JavaScript中实现“键/值”式存储可以使用Object来方便高效的完成，也就是使用对象属性作为键，再使用属性来引用值，像下面这样let student = { name: '啊呜', sex: 'male', age: 18 } 复制代码但是这种实现并非没有问题，这里的键只能是对象的属性，于是就出现了Map这一新的集...

Map与Set高频面试算法题（只出现一次的数字，复制带随机指针的链表，宝石与石头，旧键盘，前k个高频单词）(Java实现)

LeetCode 136 只出现一次的数字题目链接：只出现一次的数字题目：给一个非空整数数组，，只有一个元素出现了一次，剩余的元素都出现了两次，，请找出那个只出现一次的数字方法一：我们知道0异或任何数等于任何数，两个相等的数字异或为0，所以我们可以采用位运算，将所有的数依次异或，得到的数就是只出现一次的元素代码展示： class Solution { public int s...
