Answer:
I tried with many custom test cases and this code always gave the correct answer
but when i submit it fails all the test cases except the 1st one.
@Abhishek.1514 you can use a simple sort function also.
I’ll tell you what the comparison function for a simple sort function on a vector of strings should look like, you can modify it accordingly to fit your logic of using a priority queue.
bool compare(string a, string b) {
return a+b > b+a;
