why we are returning the values of the node instead of the nodes itself?

[@sharathkumar8338]

hi I have one questions to ask. When will you do your next Q/A session?? or is it ok to put it here?

[@crackfaang]

I will be making a discord soon where I will have a Q/A section. If it’s urgent, you can ask it here otherwise wait about a week or so until I figure out how to set things up

@@crackfaang yes my doubt is I checked job description of morgan stanley for 2+ years experienced. alongside DSA they had log of other requirements like CI/Cd, spring, spring boot and all. Do we really need to know anything else apart from DSA and system design or does it depends on company??

can't Is store the node values in a nested hashmap ? For example to store node, with value = 5 at level 2 and col = 1, I can create a hashmap as follows col : row : list of values hashmap = {1 : 2 : [5]}

[@anoopjalla8404]

this is what i did initially, and it worked

[@rsKayiira]

Thank you for this. Great solution.

[@manojamrutharaj9071]

Awesome. Thanks for the cool solution

[@syafzal273]

Great explanation!

[@LondonMoneyCashEnterprise]

i dont get why this is a hard problem, seems pretty easy enough

[@1Rashiid]

The explanation in the video is not same as the code. You did not mention that we use the row in the hashmap at all. You explain it like the medium version and then in the code you add the row... still adding the row ( the main point in this question) is not clear.
