#include <iostream>
using namespace std;

int main() {
    string engNum[10]={"zero","one","two","three","four","five","six","seven","eight","nine"};
    string s;
    int temp=0;
    int res=0;
    while(cin>>s){
        if(s == "+"){
            res+=temp;
            temp=0;
        }
        if(s == "="){
            cout<<(res+temp==0?"":to_string(res+temp))<<endl;
            res=0;temp=0;
        }
        for(int i =0;i<10;i++)
            if(s == engNum[i]){
                temp*=10;
                temp+=i;
            }
    }
}
// 64 位输出请用 printf("%lld")

不要用split的思想
