Question 817. Linked List Components Solution 题目大意:给一个链表和该链表元素组成的一个子数组,求子数组在链表中组成多少个片段,每个片段中可有多个连续的元素 思路:构造一个set用来存储子数组元素用于判断是否存在,遍历链表,如果当前元素不存在而下一个元素存在就表示一个片段的开始了,遍历前先判断首元素是否存在 Java实现: public int numComponents(ListNode head, int[] G) { Set<Integer>…

题目标签:Linked List 题目给了我们一组 linked list, 和一组 G, 让我们找到 G 在 linked list 里有多少组相连的部分. 把G 存入 hashset,遍历 linked list, 利用 hashset 来检查目前的点 和 下一个点 是否在G 里面. 如果目前的点在G里面,下一个点不在,说明这里断开了.具体看code. Java Solution: Runtime:  7 ms, faster than 81 % Memory Usage: 40 MB, l…

链表基础 链表(Linked List)相比数组(Array),物理存储上非连续.不支持O(1)时间按索引存取:但链表也有其优点,灵活的内存管理.允许在链表任意位置上插入和删除节点.单向链表结构一般如下: //Definition for singly-linked list. struct ListNode { int val; ListNode *next; ListNode(int x) : val(x), next(NULL) {} }; 相关LeetCode题: 707. Design…

回顾 经过昨天的优化处理([前端优化之拆分CSS]前端三剑客的分分合合),我们在UI一块做了几个关键动作: ① CSS入UI ② CSS作为组件的一个节点而存在,并且会被“格式化”,即选择器带id前缀,形成的组件如图所示: 这样做基本可以规避css污染的问题,解决绝大多数问题,但是更优的方案总是存在,比如web components中的shadow dom! javascript的组件基本是不可重用的,几个核心原因是: ① 组件实例与实例之间的html.css.Javascript很容易互相污染…
