Question

Fill in the blanks in the function below. listsum() takes a list of integers and the list’s length. listsum() gets the sum by adding the sum of the halves. Each half is recursively divided into two until it reaches the base case (a list containing a single element or an empty list).

Trace and illustrate what happens.

1. def listsum(numlist, size):
# --base case--
# if the list is empty
if size == 0:
return 0
# if the list contains a single element
elif size== 1:
return
# get the halfway point
# so we'll know where to divide the list in half
mid= size // 2
#-- recursive step
# add the sum of the left side with the sum of the right side
#tip: you need to pass the left side to one function call
# and the right side to the other
return listsum(
