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…
