Exam 01 Piscine 42 Exclusive ((full)) Instant

The 42 Piscine is a trial by fire, and Exam 01 is your first true moment of reckoning. After a week of drowning in shell commands, Git pushes, and basic C syntax, the "Exclusive" nature of this exam stems from its ability to filter those who can truly think under pressure from those who simply memorize code.

3. Solution Design

The solution is trivial when using ^. However, the exam may explicitly forbid using the ^ operator to test understanding of bitwise logic. In that case, we implement XOR via basic bitwise operations: exam 01 piscine 42 exclusive

• Too many functions (you have only one, so fine)
• Too many lines (max 25 lines per function)
• for loops (not allowed if a while is possible)
• Missing header comments

1. Handle sign.
2. Handle base validation (length >= 2, no duplicates, no '+' or '-').
3. Convert.

Shell (25% of grade)

• aff_a – Print first character of a string
• aff_first_param – Print first argument
• aff_last_param – Print last argument
• aff_z – Print 'z' and newline
• maff_alpha – Alternate case alphabet
• maff_revalpha – Reverse alphabet alternating case
• only_z – Same as aff_z
• hello – Print "Hello World"
• ft_print_numbers – Print digits 0-9

Phase 1: The "Perfect" Mindset

• Do not try to be clever. Moulinette hates clever. Moulinette loves explicit.
• Norminette is active. You will fail if you have a trailing space, a wrong newline, a missing header, or a function with more than 25 lines.
• Leaks are instant failure. Every malloc must have a free. Every open must have a close.

The Catch: You cannot see Level 2 exercises until you have a perfect score (100%) on a Level 1 exercise. If you fail a Level 2 exercise, you can go back to Level 1 to earn more points, but you lose progress toward higher levels. This exclusive linear progression forces perfection at lower levels before tackling complexity. The 42 Piscine is a trial by fire,
