Na to máme sorty. Je to rodina algoritmov ktorá každá funguje nejak inak a má rôzne výhody a nevýhody. V tejto prednáške si ich popíšeme. Min sort: Min sort je algoritmus ktorý je veľmi jednoduchý. Prejde celé pole a nájde v ňom najmenší prvok, ten dá na začiatok ďalšieho poľa a odoberie ho z pôvodného.https://yastrab1.github.io/prednasky/funkcie/Fri, 11 Jul 2025 00:00:00 +0000https://yastrab1.github.io/prednasky/funkcie/Funkcia je veľmi jednoducho kus kódu ktorý by sme radi niekedy zopakovali len s drobnými zmenami. Jednoduchý príkladad v Pythone je napríklad: 1 2 3 4 5 6 7 def plus_dva_krat_dva(cislo): vysledok = cislo*2+2 return vysledok print(plus_dva_krat_dva(2)) # Outputs 6 print(plus_dva_krat_dva(1000)) # Outputs 20002 ... Je tu toho na začiatok viacej. def je kľúčové slovo v Pythone ktorým definujeme funkciu. V zátvorkách sa nachádzajú jej parametre. Parameter je tá drobná zmena v funkcií - napríklad chceme rôzne čísla vynásobiť 2 a pripočítať k nim 2 - preto si definujeme takúto funkciu.https://yastrab1.github.io/prednasky/procesoroveoptimalizacie/Fri, 11 Jul 2025 00:00:00 +0000https://yastrab1.github.io/prednasky/procesoroveoptimalizacie/Rád by som na začiatok začal s takým motivačným príkladom. Mám tu dve funkcie ktoré sčítajú obsah poľa v c++. Ktoré si myslíte že bude rýchlejšie a o koľko? 1 2 3 4 5 6 7 8 9 int sum_1(int** arr) { int sum = 0; for (int i = 0; i &lt; arr_size; i++) { for (int j = 0; j &lt; arr_size; j++) { sum += arr[i][j]; } } return sum; } 1 2 3 4 5 6 7 8 int sum_2(int** arr) { int sum = 0; for (int i = 0; i &lt; arr_size; i++) { for (int j = 0; j &lt; arr_size; j++) { sum += arr[j][i]; } } return sum; Pri kompilácií s g++ main.https://yastrab1.github.io/posts/2024/06/my-first-big-arduino-project/Mon, 24 Jun 2024 17:25:07 +0200https://yastrab1.github.io/posts/2024/06/my-first-big-arduino-project/For the past few years, I have been playing a bit with the microcomputer Arduino. In fact, I have actually learned how to code using the simplified Arduino C language. And this year, I saw a great opportunity to make a bigger projects. Every year in our school, we have to pick a topic that we make a project from. We have a whole year to finish the projects, and it leads to some great ideas being brought to light.https://yastrab1.github.io/posts/2024/06/about-this-blog/Fri, 14 Jun 2024 13:15:15 +0200https://yastrab1.github.io/posts/2024/06/about-this-blog/Hi! Welcome to my own blog! This blog is meant for showing off my projects that I had been doing in the past 8 years I know how to code. I like to experiment a lot and make a lot of different prototypes - just in python - my go to prototyping language - I counted ~ 57 projects As all of my other projects, this blog is a prototype. Maybe I will stop posting here in a month, maybe in a week, i don&rsquo;t know.https://yastrab1.github.io/achievements/Fri, 14 Jun 2024 13:04:01 +0200https://yastrab1.github.io/achievements/Math 🏆 Náboj JUNIOR 2023 Math competition for teams of 5 - 1.

My name is Lukas and I am a young enthusiastic software developer. I like to spend a lot of my time experimenting with prototype projects, so is this blog. I learned to code when I was 6, and since then, I have done few cool things. For example, my submissions in our schools game jam, Špongia (our team page) I had an internship in Mindfloat where I learned how software is done in corporations.
