Can the chart and algorithm be drawn for a large input data set?

[@stephank.murphy4874]

So in summary, always go from the root in counterclockwise direction around the tree.
- For Pre-Order, print the nodes as you visit them for the first time.
- For In-Order, print the nodes only when you visit them for the second time.
- For Post-order, print the nodes when you visit them for the last time.
Kudos man, that is succinct and sticks. Great job.

[@pieosaurus3]

2 different professors have tried to teach me this and I did not understand it. This 7 minute video explained it better and WAY faster than them. Thank you so much!

​@@techdose4uthank you for explaining. Albert Einstein once said if you can not explain something in simple terms, that means you have not understood the problem enough. You sir are clearly more knowledgeable than most profs

[@nikolasioakimidis3003]

While yes, it's the fastest and easiest way, you don't really understand what's happening and why you are doing what you are doing. Don't get me wrong, this is an amazing video but every technique has its pros and cons

[@RamprasadKaranth]

You must be kidding ... You have successfully trolled all the professors out there .. This is a godsend !

The post order explanation was 🤯 GENIUS “has been reached for the third time” is the easiest logic ever

[@techdose4u]

Thanks :)

[@nosiphokhumalo656]

I think this is the third time I'm watching the video, have wrote tests without fully understanding this but after today I got it a 100 percent, the post-order was well explained thank you so much

I feel many professors try to dance around the simple way these traversals work and try to teach tricks on how to remember them like with post order being bottom to top (with left to right) but actually going over them in this simple demonstration helps much more.
