In case you were wondering, this is still super helpful to people (at least, me!) 7 years later. Thanks.

I have watched many videos about this topic but your explanation is outstanding

Absolutely phenomenal explanation, goes over every little detail so you can't possibly feel lost at any one step. Couldn't for the life of me figure it out with the textbook or the other weird videos where they use a table and formulas that seemingly come out of nowhere, but this made it abundantly easy to understand. One watch and I could execute it flawlessly :)

I know you uploaded this seven years ago but from all the different videos on explaining this method, you're the one that did it in a clear way that I can actually understand. Thank you.

GREAT explanation. As others have noted, treating the numbers as variables is what ultimately unlocked this for me. It's so unlike anything I've done previously in my limited math experience, I could not tell what was happening until this video made it clear. Thanks a lot!

With this video, solving recurrence by substitution is tick. Thanks for the video although its like more that 5 years since the upload, it is still helpful.

You are the hero in the night. The dancing of the flowers in the wind. The moonlight dipping into the sand. Thank you John. On all my next exams, I will write “This one’s for John.” before all recurrence relations.

@rayjennings18616 ай бұрын
I think that it's worth noting that each node splits into two branches due to the "2T" part of the recurrence. If it were 3T then there would be three branches from each node, etc.
@rayjennings18614 ай бұрын
If the coefficient is bigger than 3 it's still doable but if the branches grow at the same rate. The key is to find the height of the tree for the asymptotic runtime and if the branches grow at different rates then I usually take the one that grows fastest then use the substitution method to verify. Easier said than done of course. CLR 3rd Edition has an example like this.

At 3:40 when the 2's cancel, I don't understand why its still 2^2 if we used one of the twos to cancel out denominator and get 4n. I am confused. Can someone explain?
