题目传送门 题目描述:给出n,x,mod.求s[n]. s[n]=s[n-1]+(x^n)*(n^x)%mod; 思路:这道题是hdu5950的进阶版.大家可以看这篇博客hdu5950题解. 由于n很大,所以肯定是矩阵快速幂的题目,但是矩阵快速幂只能解决线性的问题,n^4在这个式子中是非线性的,后一项和前一项没有什么直接关系,这里要做一个转换,把n^4变成一个线性的,也就是和(n-1)^4有关系的东西,而这个办法就是: n^4=(n-1+1)^4=(n-1)^4+4*(n-1)^3+6*(n-1…

传送门:A Simple Problem 题意 给定两个序列s1和s2,同样的数字可以用相同的别的数字代替(并且也可以是出现过的数字),问s2在s1中出现了几次. 题解 首先预处理一下这两个序列,因为数字的位置是不会变得,所以把每个数字用当前位置和前一次出现的位置的差表示,如果是第一次出现,用-1表示,这里为什么是-1呢,不能比-1更大,但可以更小,不然如果匹配的时候 j=0,那么如果 s[i]=0 这样判断的就是不是该满足的那个条件了,这样是不对的.然后就是kmp匹配了,匹配的判断条件改一下就…
