Hey Codeforces

I am well aware that we shouldn't use unordered maps in our solutions because they lead to tle in certain cases

I came across some solutions using unordered map for the 4th Question in the recent Edu Round. I tried generating a testcase in which these submissions tle but failed to do so

Can anyone help me out in this

Submission 1 : 273573097 Submission 2 : 273588275 Submission 3 (Its in Java but shouldn't it use TreeMap instead of Map ? ) : 273571369

Thanks a lot :)
