Sir i am not getting output?

#1

#include
#include
using namespace std;
bool compare(string s1,string s2)
{
if(s1.size()<=s2.size() && s2.substr(0,s1.size())==s1)
{return false;}
else if(s2.size()<=s1.size() && s1.substr(0,s2.size())==s2)
{return true;}
else return s1<s2;
}
int main() {
int n;
cin>>n;

string s[100];
for(int i=0;i<n;i++)
{
	getline(cin,s[i]);
}
sort(s,s+n,compare);
for(int i=0;i<n;i++)
{
	cout<<s[i]<<endl;
}
return 0;

}

update the way of taking input
string s[n];
for (int i = 0; i < n; i++)
{
cin >> s[i];
}
