Comment résoudre les tâches ?

1 - Read the task and understand what needs to be done

2 - The example shows how the input data will be provided and what output is expected

3 - Write the code considering the input, output, and the task itself.

Différence entre Exécuter et Vérifier tout

1 - The “Run” button executes your code only on one set of input data, and you’ll see the result in the output window.

2 - The “Test on All Cases” button runs your code against all test cases. If all tests pass, a banner will appear. If even one test fails, it will be highlighted in red.

Comment modifier les données d entrée

To change the input data, click the “Run Test” button next to the input data you want to execute.

Travail avec fenêtres E/S

1 - Input Data is the window containing the values loaded into your program in place of input()

2 - Program Output is the window showing what your program prints. If it’s green, the output matches the expected result; if red, there are differences.

3 - Expected Output is the reference value used to verify the solution.

1 - Green means the program produced the correct output

2 - Red means the program’s output didn’t match the expected output for this data. The program output and the expected output must be identical, including spaces and punctuation!

Criteria for a Correct Solution — How to Know It’s Right

If you see this banner, congratulations — everything is correct.

Topic Structure (30 Tasks: 10 Easy, 10 Medium, 10 Hard)

1 - The first 10 tasks are quite easy and contain hints covering only the essential parts of the topic.

2 - The next 10 tasks are medium difficulty. Their hints differ from the easy ones and reveal new aspects of the topic.

3 - The hardest tasks have no hints. Often, they include additional topics, so sometimes it’s better to move on and return later. Read the hints carefully — they offer new ways to solve already familiar problems.

Availability of Theory (Video + Text)

1 - Each block contains a “Theory” section.

2 - It always includes a detailed video.

3 - There is also a detailed guide with all the necessary theory and code examples.
