1、为什么不能用数组实现队列 因为用数组实现元素个数是固定的,不便于插入和删除。因此,用链表实现更合适。 2、链表结构 注意点: In a single linked list, the address of the first node is always stored in a reference node known as “front” (Some times it... ...
Implement Quicksort in Java using LinkedList (Takes the median as pivot) public class QuickSortList { public ListNode sortList(ListNode head) { if (head == null || head.next == null) { return head; } ListNode mid = findMedian(head); // O(n) ListNode leftDummy = new ListNode(0), ...

Forming groups in GROUP BY Removing duplicates in DISTINCT 在这样的场景下 hashing 是更好的选择,它能有效减少排序所需的额外工作。 Hashing Aggregation 利用一个临时 (ephemeral) 的 hash table 来记录必要的信息,即检查 hash table 中是否存在已经记录过的元素并作出相应操作: DISTINCT: Discard duplicate GROUP...
