Hey @sulbh579 the testcase is not working because your output of strings in not correctly sorted as per the requirements. If you observe closely though, the required order of output is the reverse of your initial vector v
before sorting as per your comp function.
So instead of doing the sorting do this
for (auto it = v.end()-1; ; --it){
cout << *it<<’ ';
if(it==v.begin()) break;
}

Now the code works fine but if you still have any further doubts, please feel free to ask;
