Intro To Competitive Programming Course

Jupyter Notebooks for teaching Competitive Programming simply.

Click "launch binder" above to launch the exercises in Binder, a read-only environment for Jupyter Notebooks. This means that your progress will be erased when the browser tab is closed. Download the notebook files you wish to keep: right-click on the file and click "Download". Alternatively, follow Method 2 below to install Python on your local machine and learn from there.

Content of this course is largely adapted from Steven and Felix Halim's excellent book "Competitive Programming 3".

How to access the notebooks properly

Method 1. Using Binder

1. Click "launch binder" above.

2. Wait for the binder instance to start. If you see a message Too many users on this BinderHub! Try again soon., try to reload the page after a bit.

3. Once binder has loaded, click on Course Files.

4. Inside the Course Files folder, there are subfolders of the modules of the course. Each subfolder will (at least) contain:
   • One notebook for the content
   • One notebook for the problems relating to the content in the first notebook
   • One directory for the PDF documents of the problems
   • One directory for the solutions to the problems

Double click on a notebook to open it.

5. After selecting the python interpreter (Python 3 (ipykernel)), you can use the toolbar to run cells.

Method 2. Using Jupyter Notebook Locally

First you'll need to install Python. This course uses Python 3 (more specifically Python 3.8 and above), so you'll need to install that first. Python 3 can be downloaded from Python.org.

• Choose the Python 3 version that suits you. This course assumes that the Python 3 version chosen is 3.8 and above.

Next download this repository and unzip it. A folder named Intro-To-Competitive-Programming-main should be obtained.

Now open up the Command Prompt (on Windows) or Terminal (for Unix) and navigate to the Intro-To-Competitive-Programming-main folder. You can do that by running

cd [ENTER_THE_PATH_TO_THE_FOLDER_HERE]

in the console.

Once there, run

python -m venv venv

or

python3 -m venv venv

if the above command does not work. This creates a virtual environment for you to open the notebooks. Next, run

source venv/bin/activate

to actually activate the virtual environment. A prompt near the start of the console like (venv) should appear.

Now, run

pip install -r requirements.txt

to install the needed requirements for opening the Jupyter notebooks.

Finally, to actually start accessing the Jupyter notebooks, run

jupyter notebook

In the future, to access the Jupyter notebooks easily, navigate back to the folder (from the Console/Terminal) and run the following commands.

source venv/bin/activate
jupyter notebook
