'''
* Implement a function known as all(iterable). This function returns True if all of
the elements of the iterable is True or the iterable is empty, else False.

* Implement a function known as any(iterable) . This function returns True if any of
 the elements of the iterable is True . If the iterable is empty, return False.

* Implement the abs(x) function where x , is a number.

* Implement a function that returns the minimum and maximum numbers in given list. 
Don't use the built-in function min and max.
