#4 
 if(s[i].find(s1)!=string::npos){
            cout<<s[i]<<endl;
            return;
        }

s[i].find(s1) this will find the string s1 inside s[i]

The position of the first character of the first match.
If no matches were found, the function returns string::npos

if the s1 find in s[i] then it print s[i] and return;

i hope this helps
