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.

Best CS tutoring video comment I have ever seen in my life. You are true god
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!

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

Remember Inorder as DFS
These 7 minutes were the most productive 7 minutes i have ever spent on anything.
The post order explanation was 🤯 GENIUS “has been reached for the third time” is the easiest logic ever

3 years ago and still helping tons of people, thanks for this amazing explanation dude, you seriously rock! I'm definitely sharing this with my Uni mates.
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

showing the null values under the leafs was really helpful and made me actually understand how each traversal algorithm was different, something my prof couldn't do, and in only 7 minutes! wow
This is strategy is so good. I don 't understand when just the concept is being taught, i only get the concept while explaining an example like this. TY.

Thank you so much, because of you I'll end up passing my exam. This made what my lecturer was teaching seem so easy
Thank you for this excellent visualization! Including the null child trees really made all the difference!
This is great man, I have spent 4 hours in class without understanding anything but just within 7 minutes I got everything very well!
Lmao, took dsa in my community college and now again at a 4 year just because its more rigorous at this school and I always come back to this video for traversals of binary trees, thanks for doing the lords work

Thanks for this wanderful work that has set me free from understanding pre- order, in-order and post-order.
This is so simple! Yet most of the professors leave you confused after 3 hours of lecture!
Actually amazing. I was trying to figure it out by myself and when I though I got it i realised I did everything wrong xD Thanks for this amazing method, super easy!
It's the most easy way to do it....great explanation ...Thanks alot sir 💞💞
Amazing method, you have converted 2 hrs lec in just 7 minutes!!!! thanks a lot sir :)))

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.
Amazing and mind-blowing trcik sir tqq so much for giving this lecture .no one said like you.we need a professor like you sir
Thank you very much for that video. I didn't understand that topic during the lectures at my university, but now it's easy for me :)
