Errichto, when you first released it, I didn't understand the concept of it, but decided to save it in my playlist to watch it later. Today, I was solving the daily challenge on Leetcode and suddenly remembered your video. Watching it now, things start clicking for me. Thank you so much. Please make more videos like these.

Your videos are the reason I started competitive programming 🙌 thanks a lot!

Cool, good luck!

I like how you smile when you explain the concept, shows your deep love for the art! A pleasure to learn from you !

I truly appreciate the "over-explanation" of even the more simple concepts. If anything it is a reinforcement that helps drive the concept home, instead of just skimming over it without any actual absorption.

The Overall Quality of videos are getting better great work indeed! waiting eagerly for Gaussian Elimination.

I had already solved this problem recursively before but I didn't understand the iterative solution until watching this video. Your explanation and visualization was really helpful. Thanks!

Errichto , The picasso of CP👌🔥

Waiting for some more advanced stuff to come :) This videos are really great

wow another video, i thought your stream was planning a lot. thanks for your dedication, remember not to push so hard that you burn out! youre perhaps even the best educational channel i've seen, the way you explain things helps you understand how to get there too.

Great content Erricto!.would be great to see some videos in the future on segment trees as well!

Errichto you are a savior.... Please keep up doing this good work ... This matters a lot specially in the countries with small per capita income...

Thank you very much, you have a natural talent to explain clearly and make it easy.

Thanks Errichto! This is good and easy explanation for fast-power (Binary Exponentiation)

Thank you! Your explanation for this algorithm is awesome!

i wasted my time in another video watching it again & again trying to figure this out this made it crystal clear covering every doubt the previous video created like the shift and mod ones

your article is just awesome

Wonderful explanation ❤️! Understood every little thing. Thankyou 🙏

thats very good!! please do cover diophantine equations, fft etc as well...and in such topics maybe include popular question and variations thanks!!

Thanks much... keep doing these kind of videos.. really helps!

thank you for your wonderful explanation... you are an amazing teacher .

This was super helpful for my cryptography class thank you!

Really good explanation. Ty!

This video helped a lot. Thanks Man.

Love your video errichto ❤

Thank You, explained really well.

Thank you for a perfect and easy explanation😄

Great way. Its very nice than previous.

great video. It would be awesome if you could make a video on Merge sort tree.

awesome video bro. take ❤️ from 🇧🇩

Another great video. 😊

Best explanation of binary exponentiation

Thanks man. Keep it up

I always thought why we studied this multiplication in principle of programming language. Now I know. Thanks

can you make some videos about fractals in action? also, you're videos are *CRAZYYY* you're so good at explaining stuff

Fine answer. Thanks ❤️

Thanks for the explanation

I like the new background 👍

wow u also have great teaching skills ..Thanks for helping

Hey, Errichto thanks for the video. Can you also put some questions link in your description box?

great explanation !

really helpful content :)

When the Matrix expo is coming? We have been waiting for a long time now, looking forward to the new video

Kamil, we need more videos from you. :D

12:10 Thanks, man :D I thought I was the only one.

Thanks a lot man!

Very helpful 👍

Are you kidding me ERRICHTO!! How can you read my mind for what topics i need????

Thank you a lot ❤ Can you please recommend some problems to implemented as a training... Thanks again ❤❤💙💙💙

Thank U, U are awesome 🤘🌨❄

It amazing how there exists and algorithm to create an output of size B*log(A) in time log(B).

@Errichto

The complexity O(log(B)) assumes that multiplication is done in O(1). This makes sense because we mainly compute a huge power modulo P.

Great video you upload 👌 I myself make computer science videos . Can you tell me which mic do you use ?

can u please make a video abot how to setup your cp setup - how to download and use yor ide? would also like to see some c++ toturials tank you very nuch!

Hi Errichto, I am a subscriber of your KZread channel and admire your work alot.Wanted to ask for an advice , how to learn solution of a problem when it's solution is not present anywhere on internet. Even if I get a hint it's easier. But there are some problems like asked on an interview whose solution afterwards I get nowhere in internet. How to learns solutions of such problems?

Damnnn.. love you

can you tell about left to right binary exponential

Waiting for the next one...

Hey what if I remove the 0 condition instead of 1. why just if(b==1) return a is not correct ?

So neat

Can you do a video on Matrix Exponentiation?

can you please explain how to find PRIMITIVE ROOTS,? and EULER'S TOTIENT FUNCTION.

@errichto *please* make a video on Segment tree *iterative* with *lazy propagation* , everyone teaches recursive one, with memory 4*n and 5 arguments !! non recursive if okay till point updates, but range updates ( lazy propagation ) seems way too complicated. please make a video on *lazy update* on *non recursive segment* tree, we belief you will make it simpler, and also no video on you-tube exists on it.

How to calculate pow(a,pow(b,c)) under modulo

If a^-b how we can slove it please

You can calculate 9^9 I remember that it's 387420489 But it doesn't really matter

Problem: You are given a sequence of length n. Apply to it a given permutation k times. Solution: Simply raise the permutation to k-th power using binary exponentiation, and then apply it to the sequence. This will give you a time complexity of O(nlogk) Can anybody explain what its talking about ?

I don't understand the iterative part, is there any other simpler way to understand this?
