answer

#include <bits/stdc++.h>
using namespace std;
void solve(){
	int n,sum=0,ans=0;
	string s;
	cin>>n>>s;
	for(int i=0;i+3<n;i++) if(s.substr(i,4)=="CCPC") sum++;
	for(int i=0;i<=n;i++) for(int o:{0,1}){
		int v=sum;
		for(int j=max(i-3,0);j<i&&j+3<n;j++) v-=s.substr(j,4)=="CCPC";
		for(int j=max(i-3,0);j<=i&&j+3<=n;j++) v+=s.substr(j,i-j)+(o?"C":"P")+s.substr(i,3-i+j)=="CCPC";
		ans=max(ans,v);
	}
	cout<<ans<<"\n";
}
int main(){
	cin.tie(0)->sync_with_stdio(0);
	int t;
	cin>>t;
	while(t--) solve();
	return 0;
}

这程序好像有点Bug,我给组数据试试?
