Do not look at the solution. Fire up the jcluzet/42-exam simulator. Start at Rank 02. Try to solve Level 0 (aff_a, first_word). If you fail, look at the Moulinette's error output, not the code.
Unlike traditional academia where exams test memorization, the 42 exam tests resilience and logic. You are placed in a sandboxed Unix environment (usually a Docker container or a dedicated Ecole 42 VM) with a shell, a text editor (vim, emacs, or nano), and a series of exercises that escalate in difficulty.
The catch? No internet. No man pages (sometimes). No Stack Overflow. Just your brain and the tools provided. 42exam github
The infamous "Exam Rank" system (Rank 00 through Rank 06) determines your progression. To pass your "piscine" (the month-long bootcamp intensive) or to validate a circle in the core curriculum, you must hit a specific percentage on the exam.
The most popular and actively maintained repository is 42-exam (user: jcluzet). Do not look at the solution

If you want to maximize your success using these resources, follow this workflow:
A GitHub repository related to the 42 exam, such as those named 42exam, usually contains resources, practice problems, solutions, or tools related to preparing for or taking the exam. These resources might include: Language: Go
A word of caution. 42’s evaluation system (Moulinette) is brutal. It cross-references submissions. If you blindly copy-paste a solution from a public 42exam github repository, two things will happen:
Do not copy. Instead, use these repos as a textbook. Rewrite the code from memory. Change the variable names. Understand why a while loop is used instead of a for loop. The only way to pass is to internalize the logic.
