Wrong Coding question in PH test held on 23/01/22

There was a question in coding round in which we were supposed to input name of cities and return the connected path.
so basically we were supposed to return a connected path in the given graph and it was provided that the path exists at in all test cases

This question had a major problem as number of input was not defined nor any end of line indication was provided.

This never allowed our program to stop taking input.

I couldn’t report it during the test so now I’m looking for ways to report it here.
