Also: A Priority Queue is not a list that sorts itself, it is a queue that always returns the element with the highest priority next (usually the lowest value in a list of numbers). As a matter of fact, PQs usually get implemented using a Min-Heap (which, by keeping the heap invariant true, has always the lowest element as its root). Important to understand is that a PQ is not a list but a queue (a First-In-First-Out data structure which makes it impossible to do index calls) and is not (fully) sorted but only gives back the element with the highest priority / lowest value. Of course you can easily implement it by sorting a list once an element has been added but that is usually not how it is done because the computational overhead it generates for the little (to no - in a PQ we don't care about any other element than the next) benefit it gives us. Operating on a large dataset this can significantly affect the performance. You based your explanation on your implementation and while the implementation of course works the explanation of a PQ is wrong. Just something I wanted to mention but other than that, nice video as always!

Amazing pronunciation on everything, even "VM7WC".

Loving these videos. Hope you keep making more

I SHOULD HAVE EXPECTED "IT" AT THE END

firstly I would like to wish you well and to say a huge thank you for uploading these videos as they have been an invaluable resource to

I was on my university’s first real programming team. There were so few people interested that we didn’t even have to try out. We just volunteered and we were instantly on the team. We didn’t have enough time to learn all the relevant algorithms so my position on the team was to solve problems that nobody knew the algorithm for lol. I remember one of my ad hoc solutions being too slow for the judge so we wrote code that printed out a C array of the first 100 primes. Then we took that array and hardcoded it into the solution to reduce the final processing time.

Glad you managed to put Bad Apple in again. I felt it's abstinence in the last video. 10/10

Thanks for your easy to follow explanations, one step at a ti. It makes learning less overwhelming!

Your videos are quite often the highlight of my day

Wow this sure would've been helpful in my first ever competitive programming contest last week wow truly a crazy world am I right

I've been waiting for this kind of video for a really long time.

i understood less than usual and laughed more than usual, banger video thank you Junferno 🙏

As a competitive programming nerd who took part in the Sud West European Regional Contest for ICPC of last year (my team lost, since we're not Russian), I can attest that this video is truthful, and also that competitive programming is a great source of -frustration- satisfaction.

Currently preparing for British Informatics Olympiad this year, I open KZread and see new Junfero competitive programming video with anime woman in thumbnail, nice algorithms very cool

Great style. Excited to see your next video.

I love how your videos have the power of curing my depression even though I've literally never coded anything in my entire life

Very nice surprise to see my country in your vid. Your pronounciation is on point! Having been to all these places myself I guess I have to agree with you :D The dijkstra guy kinda reminds me of walter white for some reason

Cool video! Honestly learning all the graph + sorting algorithms seems fun

How is He putting so much information into my brain so fast. This video is 12 minutes long, and I feel like I've watched 1 hour long video essay.

First time to your channel and I accidentally got an explanation of the Dijkstra's algorithm. Came for the thumbnail, stayed for the informative tutorial (can I call it a tutorial though?). Anw, thank you and can't wait to see more videos like this.

now im a god thank you junferno

I didn’t really understand this video when it first came out but now but now it finally makes some sort of sense. I was learning about weighted graphs in data structures and algorithms today and instantly remembered this video

Hey! Thanks so much for this video!

I am fuckin SCREAMING at the ending, Juneferno strikes again

Damn, I loved the way this vid was put was together subbed XD

I just want to say that I love your content.

the final problem reminds me of that way of decrypting a decryption key with only one one pair of encrypted/decrypted messages. instead of randomly guessing 100 different consecutive decryptions (a already encrypted encryption is recrypted several times to increase security) in order to find the proper decryption key, one can instead guess 50 decryptions on the encrypted message and do 50 reverse encryptions on the decrypted message and meet in the middle and compare all of the different half decrypted keys and see which ones match. Because the time needed to break an encryption increases exponentially with every layer of encryption, decreasing the time needed from t^100 to 2*t^50 where t is the time to guess a single layer of decryption is an extremely effective method. Thus, it is also extremely hard to have 2 middle points instead of 1 because there is no secure launching point to 'save progress'.

I am very glad that I stumbled upon your video

This was interesting and very funny, good job Junferno! As Captian Falcon would say, "I lika ya moves!"

Your pronunciation is... Excellent. Very respectful to learn it!

I clicked on your video because the thumbnail has to be the most eye catching thing ever. What does misato have to do with competitive programming? I‘ve seen it now and I am unable to turn down my urge to get an answer for the question. Props to that. Genius.

I'll be totally honest here: really, the main reason I clicked on this video is because I saw Misato in the thumbnail _{Misato Katsuragi best Evangelion girl}_
