这么简单的题目没人发题解

挨个枚举

#include <bits/stdc++.h>
using namespace std;
#define int long long
string s;
int sum;
signed main(){
	getline(cin,s);
	for(int i=0;i<s.size();i++){
		if(s[i]=='a' || s[i]=='d' || s[i]=='g' || s[i]=='j' || s[i]=='m' || s[i]=='p' || s[i]=='t' || s[i]=='w' || s[i]==' '){
			sum++；
		}
		if(s[i]=='b' || s[i]=='e' || s[i]=='h' || s[i]=='k' || s[i]=='n' || s[i]=='q' || s[i]=='u' || s[i]=='x'){
			sum+=2;
		}
		if(s[i]=='c' || s[i]=='f' || s[i]=='i' || s[i]=='l' || s[i]=='o' || s[i]=='r' || s[i]=='v' || s[i]=='y'){
			sum+=3;
		}
		if(s[i]=='s' || s[i]=='z'){
			sum+=4;
		}
	}
	cout<<sum;
	return 0;
}
