Yeah bro. Even last problem has been copied from hackerrank. For your doubt.

They eliminated few words from the statement to make it look difficultđ

Problem statements are really bad. The author did not succeed in adapting the problem copies from hackerranck or hackerearth.
Even example or input arenât flawless .

And even having wrong answers for his own problems. XD.
