I just watched day before to my interview and I was called today to be hired. Going to donate full of my first salary.
Done ?
???
Sure, I’ve completed my sentence.
გამიხარდა ქართველის კომენტარი აქ და თან გამიკვირდა :დ

This guy is the best! I just wanted to brush up on this topic and stumbled upon this precious lecture. Now I want to watch all his lessons 🤓👍
I love that he goes over all the common mistakes people often make on the first try! It's very normalizing to see him show those mistakes, makes me feel much better lol, and also the explanations of those mistakes dig deeper and improve our understanding.
Alvin was born to teach anything coding related I'm certain. Got introduced to him while going through app academy and everytime i see a video of his I'll watch it several times over. Ofc I try to make an independent attempt at understanding but the amount of clarity that comes from him is amazing. Thank you
This was a great video and very well organized. I finished watching the whole video while coding the problems on Visual Studio Code in Python and now feel I have a good grasp of BFS, DFS, especially using recursion which I struggled with before. Thank you Alvin!
did you code binary tree in python yourself? or is his code available in python somewhere
? TIA
@@kowshikthopalli866You can implement any code of any language once you have good grasp over the language you are learning
Amazing videos alvin,got the clarity of thought needed for solving problems recursively and also dynamic programming doesn't seem a giant anymore
ahh man , this is exciting to hear.
NOT confusing explanation, soothing and clear voice, so glad I found you! great work! thanks Alvin
Great video on Binary Trees. I was struggling to solve basic problems in Binary Trees and then i finally stumbled upon this video. The way Alvin walks through the course really drills down the concept in your head and makes you feel so comfortable ! Amazing 💯
What a great course! For anyone wondering, I was able to follow along in Python despite the code being in JS with minimal issues! Would recommend
I like the way you broke down the recursion problems into base cases and general cases and tackled each one independently then combined it for the final solution. I think my issue was I tried to solve it in one go which led to me getting stuck. The recursive problems can be a real head wrecker if you're not careful!!
Thank you so much. It really helped me to understand the tree traversal in detail. Thanks again! I understood the DFS and BFS for the first time. Use of Queue and Stack for them is the key to understand the whole.
YES! Looking at the thumbnail emojis itself I knew I am gonna enjoy this video! Alvin is back!
This is an excellent video, when I sat down and really watched this thoroughly after practicing a bunch of binary tree algos, this helped to solidify even more concepts.
Thank You a lot Alvin for the great Course. Definitively Structy is the best place to prepare efficiently for interviews.
This course is so organized and clear! Outstanding work. Thanks for sharing these lessons on youtube!
The recursive depth-first traversal is essentially the same as the solution using a stack, it's just that you're using the call stack as the stack for the algorithm.
Hi bro! I followed the whole video until the end and finally did the last exercise by my own and it worked! Thanks for the lessons , i love you and wish you a Merry Christmas ♥
Covered this video in one night :D
Amazing by the speed and quality of teaching from Alvin.
Really helpful stuff, and recommend Alvin for getting prepared for DS&A.
Loved that course, your teaching style is very clear and really easy to follow 💯🎉
For the last problem, you could consider the null nodes as your base case but return 0 rather than negative infinity. In that way they would not contribute to the path sum, and you won't have to add leaf nodes in your base case as both paths would return your current node value + 0.
However, this only works knowing that the node values are positive.
Thanks! I was wondering the same thing.
This guy is the best data structure and algorithm instructor I have known so far….
no way!!!! literally found his vids on dp and graphs last week, watching this asap.
Dude, the way you explain this is impecable. Great job, please keep making videos like this ✌️
Thank you so much for all the efforts that you put through in getting this knowledge out for free. !
such a clear and helpful resource! you explain things so well!!!
hey man you rocking, since 3 years i am learning data structure and algorithm.. i never feel this much understanding.
Alvin this is an excellent video. I wish you were my teacher when I started programming!
i am jus loving the fact that these are in Js
...Thankyou sir!
Your narration is great, thank you for the educontent
Thank you Programmer Alvin! Everything is very clear and easy to follow.
it is incredible the way that you explain these challenging concepts with ease. I also watched your DP video and its amazing. Keep it going with the content
I am still trying to figure out, how is he able to understand recursion so well, explain it so well, and master it so well. 🥺
Great tutorial!! Thanks for the clear and detailed explanations!
As usual, a great video from Alvin. Thanks
Alvin is my favorite tutor in free code camp, i always watch the video he make no matter what is it about. His video about dynamic programming and graph theory is really good , you guys should check it out. 👍
Yes he is very good , have you seen his dp tutorial?
@@Jitendrakumar-gb7cn ,, His video about dynamic programming and graph theory is really good"
Legend is coming back again.
One of the best tree algo videos on YT!
I don't comment much but man...your teaching skills are awesome. You explain like how a student want a teacher should explain to them.
💯
looking forward to more videos; especially videos about optimized versions of algorithm solutions
You guys are simply the best. Thank you very much for these wonderful gems.
beautifully explained. Thank you!
Loved this course! Thank you for this.
Omg! You just simplified things a lot for me. So easy to understand! Awesome video!
Thank you Alvin. You are a great teacher.
this is such a great video for quickly getting back up to speed on trees and basic tree traversal. thank you!
Awesome course! Is there a way to print combinations / permutations using these binary trees?
Is it also possible to construct composite trees (trees with nodes with more than two children)?
Thank you!
alvin is the best instructor on this channel. his voice and explanations are clear, and the animations help so much. thank you for this free education
Much appreciate! It´s very clear and easy to follow!
Nothing short of excellent. Thanks for this video!
I really enjoy this tutorials, it is go step by step rather than throw all at once.
Fantastic! I learned a lot with this tutorial. Thanks for sharing your knowledge with us. God bless you forever! ❤💯❤
Thank you Alvin, now I'm a fan of recursion❤
Alvin is the king!! Waiting for more videos form you!
This teach is the best! He really helps us visualize those abstract topics so well, which I'm sure helps a lot of people. Thank you!
Thank you Alvin, That was an amazing tutorial on Binary tree so far.
Love this guy, keep on doing this
Thank you for this!
