S03E10 | Counting Sort Explained
Join me in my newest video presentation titled "S03E10 | Counting Sort Explained" In this episode, we'll delve into the Counting Sort algorithm, a non-comparison-based sorting technique that is both simple and efficient for specific data sets.
Counting Sort is an integer sorting algorithm that operates in linear time, making it unique among other sorting methods. It is particularly useful when dealing with a limited range of integer values. As a computer science enthusiast or a professional developer, understanding Counting Sort is crucial for optimizing your code's performance when the right conditions are met.
In this tutorial, I'll walk you through the entire process of how Counting Sort works, explaining each step clearly and concisely. We'll look at how this algorithm counts the occurrences of each unique element and uses this information to place elements directly into the correct position.
Prepare to master Counting Sort as I guide you through its inner workings, ensuring you have a solid grasp of its operational mechanism and its optimal use cases.
Be sure to subscribe to my channel to get notified about more insightful video tutorials like this one. My mission is to demystify complex algorithms and make them accessible to everyone interested in improving their coding skills.
Thank you for tuning in, and I'm excited to help you on your journey to becoming a more proficient programmer. Let's get sorting with Counting Sort!

so it can everything, except edit the content of a pdf? what a joke.
Well, it is an open source software. Maybe you can help and contribute to tehe project? I am working on it in my free time.
@@czechwisecoder idfk how to code. but I was mostly referencing the title of your video; it's very click-baity since it in fact can't edit your PDF.
@@DylanLCutshall Well, basic editation should work, including text, if edited characters are in the font.
@@czechwisecoder it doesn't work no
Hey why no full screen mode? And how to rename bookmark?
It would be nice to have a documentation.
Hello, I would like to add code to page organizer. Can you help to setup
Hello, you can start a discussion on Github.
Looks very promising! Will/does this tool allow you to add accessibility tags to a PDF document to make it more accessible to vision impaired readers?
Hello, please write an issue on Github.
Thank you for sharing!!
This is really nice.
Crazy that all of this is open source and freeware
Thank you.
Hi, You have time to answer questions about PDF4QT
the best pdf soft i have used (a Chinese 20 years OA user)
Thank you!
Thank you! I have been searching everywhere for a tool like this. It does everything I could hope for it to do! Glad to be your 100th subscriber! Again, thank you!
Thank you too!
how to install pls make demo for linux mint sir please
Hello, honestly, I would like to! But I am not a linux expert and sometimes it is crashing on linux. Please try flatpak version flathub.org/apps/io.github.JakubMelka.Pdf4qt
What library did you use to make the Software? Poppler, Podofo, Hummus? I want me make my own Pdf program as well, but am having trouble learning Qt.
Hello, I haven't employed any libraries such as Poppler, Podofo, or Hummus; instead, I have developed my own custom library. This is why it is licensed under LGPL.
Wow! A Totally awesome job very Well Done! Many Thanks to You for all the hard work you must of put in on this project I cant even begin to imagine. 👊
Thank you! I'm glad to know that you're satisfied. If you encounter any bugs or if there's a feature you believe is missing, please feel free to report the issue on Github.
Oh my! How did I discover you .... Thank You Sir - We owe you money!!!!
Thank you!
Outstanding work. Thanks. But please add the bookmark option for the pdf and also add the OCR function
Thank you for your kind words and constructive comments. I'm delighted to hear you appreciate the work. As for the OCR function, please note that while I'm not currently working on it, I have created an issue for it (#85) on GitHub. When it comes to the bookmark option, could I trouble you for a bit more detail? Are you suggesting the ability to edit bookmarks or to mark specific pages for more efficient navigation? Your further input would be invaluable in enhancing the user-friendliness and efficiency of the program.
@@czechwisecoder I am asking to add bookmarks in a given pdf for eg. a pdf with 50 pages with an index page on the front. Selection of text on the index page and bookmarking that so that whenever we press the bookmark it opens that page.
Fantastic and outstanding work by you. i have a question can i create bookmark in a given pdf
Thank you for your kind words! I am indeed planning to implement the bookmark feature for PDFs in the near future. Stay tuned for updates!
@@czechwisecoder Please release the bookmark feature as soon as possible.
'Promo SM'
Thank you for your comment! Can you please clarify what you mean by 'Promo SM'? I'm eager to understand and respond accordingly.
🎉❤Great
Thank you!
Thank you so much for this! Boy, am I glad I found this video! I am a student who simply cannot afford to purchase a PDF editor, and before this, my only option was to repaste and reformat every single element of my previous PDF document, for which I had stupidly deleted the Word file! You are a lifesaver! Thank you so much, Sir! ❤️
Hello, I am happy that you are happy with my software! Please if you find something missing, feel free to write an issue on Github.
Nice project. Nice goal,👍. Thank you for providing free pdf editor. 🎉
Thank you!
Nice
Thank you!
This is pretty awesome. Is there a way to bookmark specific pages in the Viewer Profi?
Hello, good idea. Not yet, but I will write an issue for it.
github.com/JakubMelka/PDF4QT/issues/54
Is there any OCR option available?
Hello, not yet.
Nice. Keep up the good work
Thank you.
Can you delete pages with this app?
Hello, yes, just run PDF4QT DocPage Organizer, open PDF, select pages to delete, delete them and then just export to a new PDF file via menu "Make - United Document".
