Tasks :page_curl:

• 0. Positive anything is better than negative nothing

  • 0-positive_or_negative.py: This program assigns a random signed number to the variable number each time it is executed and prints whether the number stored is positive or negative.

• 1. The last digit

  • 1-last_digit.py: This program assigns a random signed number to the variable number each time it is executed and prints the last digit of the number stored.

• 2. I sometimes suffer from insomnia. And when I can't fall asleep, I play what I call the alphabet game

  • 2-print_alphabet.py: This program prints the alphabet in lowercase, not followed by a new line.

• 3. When I was having that alphabet soup, I never thought that it would pay off

  • 3-print_alphabt.py: This program prints the alphabet in lowercase, not followed by a new line, except for the letters q and e.

• 4. Hexadecimal printing

  • 4-print_hexa.py: This program prints all numbers from 0 to 98 in decimal and in hexadecimal.

• 5. 00...99

  • 5-print_comb2.py: This program prints numbers from 0 to 99 separated by , , in ascending order with two digits.

• 6. Inventing is a combination of brains and materials. The more brains you use, the less material you need

  • 6-print_comb3.py: This program prints all possible different combinations of two digits in ascending order with two digits.

• 7. islower

  • 7-islower.py: This function checks for lowercase characters.

• 8. To uppercase

  • 8-uppercase.py: This function prints a string in uppercase followed by a new line.

• 9. There are only 3 colors, 10 digits, and 7 notes; it's what we do with them that's important

  • 9-print_last_digit.py: This function prints the last digit of a number.

• 10. a + b

  • 10-add.py: This function adds two integers and returns the result.

• 11. a ^ b

  • 11-pow.py: This function computes a to the power of b and returns the value.

• 12. Fizz Buzz

  • 12-fizzbuzz.py: This function prints the numbers from 1 to 100 separated by a space.
    • For multiples of three, Fizz is printed instead of the number.
    • For multiples of five, Buzz is printed instead of the number.
    • For multiples of both three and five, FizzBuzz is printed instead of the number.

• 13. Insert in sorted linked list

  • 13-insert_number.c: This function inserts a number into a sorted singly-linked list.
    • If the function fails, it returns NULL.
    • Otherwise, the function returns the address of the new node.

• 14. Smile in the mirror

  • 100-print_tebahpla.py: This program prints the alphabet in reverse order, alternating lowercase and uppercase (z in lowercase and Y in uppercase) not followed by a new line.

• 15. Remove at position

  • 101-remove_char_at.py: This function creates a copy of a string, removing the character at the position n (not the Python way, the “C array index”).
    • If n is negative or out of range, the function returns the original string.
    • Otherwise, the function returns the new string.

• 16. ByteCode -> Python #2

  • 102-magic_calculation.py: This function matches exactly a Python bytecode provided by ALX.
