Tasks 📃

Here are the tasks covered in this project:

0. Print a list of integers

• File: 0-print_list_integer.py
• Description: Python function that prints all integers of a list, one per line.
• Constraints: Without importing modules or casting integers into strings.

1. Secure access to an element in a list

• File: 1-element_at.py
• Description: Python function that retrieves an element from a list.
• Constraints: If idx is negative or out of range, the function returns None. Without importing modules or using try/except.

2. Replace element

• File: 2-replace_in_list.py
• Description: Python function that replaces an element of a list at a specific position.
• Constraints: If idx is negative or out of range, the function returns the original list. Without importing modules or using try/except.

3. Print a list of integers... in reverse!

• File: 3-print_reversed_list_integer.py
• Description: Python function that prints all integers of a list, one per line, in reverse order.
• Constraints: Without importing modules or casting integers into strings.

4. Replace in a copy

• File: 4-new_in_list.py
• Description: Python function that replaces an element of a list at a specific position without modifying the original list.
• Constraints: If idx is negative or out of range, the function returns the original list. Without importing modules or using try/except.

5. Can you C me now?

• File: 5-no_c.py
• Description: Python function that removes all characters c and C from a string and returns the string.
• Constraints: Without importing modules or using str.replace().

6. Lists of lists = Matrix

• File: 6-print_matrix_integer.py
• Description: Python function that prints a matrix of integers, one row per line.
• Constraints: Without casting integers into strings.

7. Tuples addition

• File: 7-add_tuple.py
• Description: Python function that adds two tuples and returns a tuple with the sum of elements.
• Constraints: If a tuple has fewer than 2 elements, the value 0 is used for the missing integer. If a tuple has more than 2 elements, only the first two integers are used. Without importing modules.

8. More returns!

• File: 8-multiple_returns.py
• Description: Python function that returns a tuple with the length of a string and its first character.
• Constraints: If the string is empty, the first character should equal None. Without importing modules.

9. Find the max

• File: 9-max_integer.py
• Description: Python function that finds the biggest integer of a list.
• Constraints: If the list is empty, the function returns None. Without importing modules or using the builtin max().

10. Only by 2

• File: 10-divisible_by_2.py
• Description: Python function that finds all multiples of 2 in a list and returns a new list of the same size.
• Constraints: Each element of the new list contains either True or False corresponding to whether the integer at the same position in the original list is a multiple of 2. Without importing modules.

11. Delete at

• File: 11-delete_at.py
• Description: Python function that deletes an item at a specific position in a list.
• Constraints: If idx is negative or out of range, the function returns the original list. Without importing modules or using pop().

12. Switch

• File: 12-switch.py
• Description: Python program that switches the values of variable a and b.
• Completion of this source code.

13. Linked list palindrome

• File: 13-is_palindrome.c
• Description: C function that checks if a singly-linked list is a palindrome.
• Constraints: If the list is a palindrome, it returns 1. If not, it returns 0. An empty list is considered a palindrome. Helper files: linked_lists.c and lists.h.

14. CPython #0: Python lists

• File: 100-print_python_list_info.c
• Description: C function that prints basic information about Python lists.
