* fix endless loop bug, divide 0 bug and update description

fix an endless bug, for example, if collection = [10,30,40,45,50,66,77,93], item = 67.

fix divide 0 bug,  when right=left it is not OK to point = left + ((item - sorted_collection[left]) * (right - left)) // (sorted_collection[right] - sorted_collection[left])

update 'sorted' to 'ascending sorted' in description to avoid confusion

* delete swap files

* delete 'address' and add input validation

Fixed error in binary_search_by_recursion 
In binary_search_by_recursion, if you search array for a value that does not exist, you will get this error:
RecursionError: maximum recursion depth exceeded in comparison

To fix this, first check to make sure that the value is between left and right points like this:
    if (right < left):
        return None

A similar construct has already been applied to binary_search, but did not exist in the recursive alternative.
