题目: [ABC288D] Range Add Query - 洛谷 | 计算机科学教育新生态 (luogu.com.cn) 大意: 一些数,选一个区间A(L~R),并再选一个区间B(长度k),这个区间B的每个数加减(加负数=减一个数)一个数,最终使得区间A全部数为0 举个例(样例) 0. 3 -1
如用户需要查找一张表,查询最后的10位用户信息,由于B+树索引是双向链表,所以用户可以快速找到最后一个数据页,并取出10条记录 聚集索引的3想成为c询(range query),即如果要查找主键某一范围内的数据,通过叶子节点的上层中间节点就可以得到页的范围,之后直接读取数据页即可 辅助索引: innodb,myisam 表中除了聚集索引...
