传送门:BNUOJ 52325 Increasing or Decreasing题意:求[l,r]非递增和非递减序列的个数思路:数位dp,dp[pos][pre][status] pos:处理到第几位 pre:前一位是什么 status:是否有前导零 递增递减差不多思路,不过他们计算的过程中像5555,444 这样的重复串会多算,所以要剪掉.个数是(pos-1)*9+digit[最高位],比如一位重复子串是:1,2,3,4...9,9个,二位重复子串:11,22,33,44,...,99,9个:…

 Oulipo 题目大意:给你一个字符串,要你找到字符串包含指定子串的个数 只要你知道了KMP,这一题简直不要太简单,注意STL的string是会超时的,还是乖乖用char吧 #include <iostream> #include <algorithm> #include <functional> #include <string.h> using namespace std; typedef int Position; ], Word[]; ]; voi…

Oulipo Problem's Link ---------------------------------------------------------------------------- Mean: 给你一个模式串P和一个母串S,让你统计P串在S串中出现的次数. analyse: 一开始想到的就是使用KMP,就用KMP写了,93ms,挺快的. 我又用AC自动机写了一遍,万万没想到竟然超时了. 后来看别人有用字符串hash写的,于是又用字符串hash写了一遍,代码30+行,而且速度也挺快…
