Coding Test A to Z by a World Finalist (with Python)

Hello.

We would like to provide guidance on how to take the course in light of the recent news regarding the closure of the Baekjoon service.

The existing lectures are structured to utilize the Baekjoon website for reviewing problem descriptions and using the code grading functionality. Accordingly, to ensure no disruption to your learning after the service ends, we plan to carry out sequential supplementary work for the problems covered in the lectures by April 28, 2026, the scheduled termination date of the Baekjoon service.

The supplementary work will proceed as follows.

1. Creation of Problem Description Materials
We plan to create and provide explanatory materials for each problem covered in the lecture to help you understand them. This will ensure that you can follow the lecture content even in situations where accessing the Baekjoon site is difficult.

2. Creation and Provision of Test Cases
While it is difficult to provide the exact same grading environment as Baekjoon, we plan to create and provide test cases so that you can verify the solutions for each problem. We will prepare these so that students can continue their studies by checking their own solutions.

Additional details will be announced and provided through updates to the lecture materials as soon as they are finalized.

Thank you.
