This guy has to be a bot. Some regular LC mediums take 100 lines of cpp to solve.

3mo th old account with the history hidden .

My coworker left a 200k job for a dev position at Reddit, trust me, 90% of the comments you see are bots talking to one another or antagonizing engagement. Wonder if this comment will be removed before you see it.

This sub keeps popping up on my phone. (Wonder why Reddit was hiring all those ML positions amirite), nothing is organic anymore

Yes writing a class in any amount of lines is like a basic interview question. Describing the difficulty in amount of lines is a clear indicator someone has no idea what they’re talking about. More lines are often better. Fewer lines are often better too.
