火中取栗

生成字符串

#include<algorithm>
using namespace std;

	char s;
	cin>>s;
	cin>>ch;
	
	for(int i=0;i<n;i++){
		if(i==0){
			cout<<s;
		}
		else{
			if(ch[i]!='a'&&ch[i]!='A'&&ch[i]!='z'&&ch[i]!='Z'){
				if(ch[i]==0&&(int)ch[i]>=97&&(int)ch[i]<=122){

			}
		}
	}
	return 0;
}
void f(int k){
	
}
int getn(){
