Related to negative test cases

#1

what we have to do when n is zero or negative
do we need to print anything or return from there?

#2

Hello @mihir_4116 no n cant be negative in this:
and if n is zero means aapke array hi empty h then you will not continue with the logic because if array is empty then you will compare on which elements.
though you will not find any such test case.

using namespace std;
bool comparator(string a,string b){
if(b.size()<=a.size() && a.substr(0,b.size())==b){
return true;
}else if(a.size()<=b.size() && b.substr(0,a.size())==a){
return true;
}else{
return a<b;
}
}
int main() {
int n;
cin>>n;
vector v(n);
if(n==0){
return 0;
}else{
for(int i=0;i<n;i++){
string s;
cin>>s;
v.push_back(s);
}
sort(v.begin(),v.end(),comparator);
for(auto x:v)cout<<x<<endl;
}
}
its showing wrong answer. can you show me where i did wrong
