[@behold_a_son]

Shouldn't it be String domain_name = email.substring(split_position +1) to start ahead of the '@'? It did not make a difference though, apparently.

[@WalkWithM3]

Nice explanation

[@NickWhite]

thanks for watching dude

[@Gideon_Judges6]

At line 11 where you do .contains and then .indexOf, you're scanning the string twice. Instead you can just do the indexOf and if it's not -1 then do the substring on that index. That should be slightly better perf in those cases.

[@jordanhanley7585]

yeah technically but the time complexity wouldn't change, so an interviewer wouldn't care

[@faizankhan-mh5uj]

too much of inner loops ?
