Exam 01 Piscine 42 Exclusive [2021] May 2026

It was a hot summer day in Paris when I first stumbled upon the mysterious "Piscine 42". As a young and ambitious programmer, I had heard whispers about an exclusive coding exam that only a select few were invited to take. The exam, known as "Exam 01 Piscine 42 Exclusive", was shrouded in secrecy, but I was determined to learn more.

As I walked through the streets of Paris, I finally found myself standing in front of a nondescript building with a small sign that read "42". I had heard that this was the headquarters of the prestigious coding school, and that the exam would be held here.

I took a deep breath, pushed open the door, and stepped inside. The room was filled with rows of sleek, black computers, and a group of stern-looking proctors stood at the front of the room. They eyed me suspiciously, but I was undaunted.

"Welcome to Exam 01 Piscine 42 Exclusive," one of the proctors announced, his voice firm but not unkind. "You have been invited to take this exam because of your exceptional coding skills. But be warned: this exam is not for the faint of heart."

The proctor handed me a sheet of paper with a cryptic message scrawled on it: "Write a program that can solve the problem of the day. You have 4 hours." exam 01 piscine 42 exclusive

I took my seat at a computer, my heart racing with excitement. I booted up the computer and began to work on the problem.

The problem was challenging, but I was well-prepared. I wrote line after line of code, testing and retesting as I went. The hours flew by, and before I knew it, the 4-hour time limit was almost up.

As I finished my program, I felt a sense of pride and accomplishment. I had given it my all, and I knew that I had produced something exceptional.

The proctors collected my paper and computer code, and I waited anxiously for the results. A few tense moments later, one of the proctors announced: "You have passed the exam. Welcome to Piscine 42." It was a hot summer day in Paris

I beamed with pride as I walked out of the building, feeling like I had just unlocked a secret door to a world of coding excellence. The "Exam 01 Piscine 42 Exclusive" had been a challenge, but I had risen to meet it. And now, I was ready to take on whatever coding challenges came my way.

Level 0: The Warmup (Guaranteed 100%)

Typical exercises: ft_putstr, ft_strlen, ft_swap, ft_strcmp, ft_putchar.

The Trap: People overthink. People use forbidden functions. The Solution: Write from memory. No loops inside loops.

Example: ft_strlen (The perfect answer)

int	ft_strlen(char *str)
int	i;
i = 0;
while (str[i])
	i++;
return (i);

Checklist:

• No #include <string.h> (using it fails the exam).
• Return type int.
• Handles NULL? (In Piscine, they won't send NULL. But if you want to be safe: if (!str) return (0);)

Phase 5 – Last hour

ft_print_combn is the hardest. Only attempt if you already have 4+ exercises correct. Use a backtracking function with a start parameter. Level 0: The Warmup (Guaranteed 100%) Typical exercises:
