5 / \ 3 8 / \ \ 1 4 9 Trace ft_btree_apply_infix (left-root-right). Write the output before running code. Give yourself 20 minutes per exercise. If you exceed, look at the solution, understand it, then redo from scratch. 4. Understand the typedefs typedef struct s_list 42 Exam Rank 03

Forgetting that base can be 2, 8, 10, 16, but not 1 or >16 per subject. Also, value can be negative only for base 10. 4. ft_btree_insert_data (Hard) void ft_btree_insert_data(t_btree **root, void *item, int (*cmpf)())

// remove from front

void *search(t_btree *node, void *ref, int (*cmp)())

> 5 EXAM FINISHED. Grade: SUCCESS. Exam Rank 03 is the first real test of algorithmic thinking in the 42 curriculum. It separates those who understand recursion from those who just copy-paste. Practice the binary tree exercises until they become muscle memory. Remember: Every recursive function has a base case (usually NULL ) and a recursive step. Master that, and Rank 03 becomes a stepping stone, not a stumbling block. struct s_btree *left; struct s_btree *right; void *item;
