题意: 给你n个盘子,这n个盘子里面分别装着1!到n!重量的食物,对于每一个询问k,找出一个最短的区间,使得区间和 mod 998857459 大于或等于k 盘子数量 n<=1e5 询问次数 m<=1e4 题解: 坑点在于此题模数998857459=4*773*2803 是个合数,因此任何a>=2803 a!=0 因此,只需考虑非0的盘子作为端点,暴力枚举$(max(n,2802))^2$个区间. 我使用的方式是记录阶乘取模非0节点的值和位置,然后求前缀和 再枚举左右端点,记录区间和取模…

基于oracle的应用系统很多性能问题,是由应用系统sql性能低劣引起的,所以,sql的性能优化很重要,分析与优化sql的性能我们一般通过查看该sql的执行计划,本文就如何看懂执行计划,以及如何通过分析执行计划对sql进行优化做相应说明. 一.什么是执行计划(explain plan) 执行计划:一条查询语句在oracle中的执行过程或访问路径的描述. 二.如何查看执行计划 1.set autotrace on 2.explain plan for sql语句; select plan_tabl…

转自:http://blog.chinaunix.net/uid-21187846-id-3022916.html       如果要分析某条SQL的性能问题,通常我们要先看SQL的执行计划,看看SQL的每一步执行是否存在问题. 如果一条SQL平时执行的好好的,却有一天突然性能很差,如果排除了系统资源和阻塞的原因,那么基本可以断定是执行计划出了问题.看懂执行计划也就成了SQL优化的先决条件.这里的SQL优化指的是SQL性能问题的定位,定位后就可以解决问题. 查看执行计划的三种方法 设置autot…
