Remove redundent function in Backtracking Sudoku (#4499)
* Remove redundent function

After reviewing this code, I've noticed that the `is_completed` function is a redundant operation.
Increasing the number of loops required for each step of the sudoku solver. 
This should remove n² operations where n is the width of the grid.

* Update sudoku.py

Remove additional newline

Mistake in maths/average_mode.py fixed. (#4464)
A serious bug was addressed with this pull request. The mode function previously
didn't return the mode of the input list. Instead, it always returned the first value.
Due to lacking tests, the bug was never caught. This pull request also adds new
functionality to the function, allowing support for more than one mode.

See #4464 for details.

* * Mistake in average_mode.py fixed. The previous solution was to returnthe
value on the first loop iteration, which is not correct, more than that it
used to delete repeating values, so result's array and check array lost
relation between each other

* Type hint added

* redundant check_list deleted

* Suggestions resolved

* output typing changed to Any
