给一个长度为\(n\)的字符串\(s\)，\(q\)次询问，每一次\(l\)和\(r\)区间内有多少个\(s_i\)等于\(s_{i-1}\)。\(10^5\)的数据\(O(N^2)\)暴力肯定行不通。于是我们考虑预处理前缀和，处理到\(i\)下标以及之前有多少个\(s_i\)等于\(s_{i-1}\)。每一次查询\(O(1)\)回

HelloWorld链接这道题是一个很明显的前缀和，我们把$sum_i$表示为前$i$个字符有多少个有重复，查询的时候就用$sum_{r-1}-sum_{l-1}$就行了。代码#include<bits/stdc++.h>usingnamespacestd;strings;intsum[300010];intmain(){ intn,q; cin>>n>>q>>s; for(in
