Function Description
Generate the code for a recursive function: furthest (n:
int, lst: list)--> int
The function returns the difference between the target
value n and the element in the list that is furthest in
value from the target n.
(ie. return the distance on
a
number line between the target and the list element
that is furthest away.)
The code should work for any list of integers with a
length greater than or equal to 1.
See sample test results below:
Function Call:
Returns:
17
print (furthest (5, [1, 3, 6, 9, 22]))
print (furthest (12, [15, 9, 16, 3, 1]))
print (furthest (5, [-5, 36, 12, 27, 6, -14, 19, 27, 34]))
print (furthest (5, [15, 61, 21, 12, 4, -25, 5, -55, 51]))
print (furthest (-10, [-5, -61, -21, -17, 16]))

Explanation:
• In the first example, 17 is the difference between
target 5 and the value in the list that is
furthest away, 22.
Restrictions:
• The built-in min(), max() and sorted () functions
may not be used.
• The list sort() method may not by used.
• The result must be determined recursively.
