I am learning OOP via Python and here I have published some of the problems I have solved. Here are the problem descriptions:

Implement a function get_largest_palindrome(n), which return the largest palindrome smaller than n. Given number n can also be palindrome.

Implement a function, called sudoku_solved(sudoku), that checks if the given sudoku matrix is solved correctly.

sudoku is a 9x9 matrix of integers.

A sudoku is solved correctly, if:

• Each row contains the numbers from 1 do 9 without repeating a number
• Each column contains the numbers from 1 to 9, without repeating a number
• All 3x3 subgrids contains the numbers from 1 to 9, without repeating a number

Implement a program that takes a string, representing a polynomial function and returns / prints the derivative of that polynomial function. Example:

f(x) = 2x^3 + 3x + 1

f'(x) = 6x^2 + 3

Implement a queue without using the append() method.

Implement a linked list in python with pop, remove and add_element methods.
