Answer 1

Answer:

Explanation:

The following code is written in Python. It creates a method for each one of the questions asked and then tests all three with the same test case which can be seen in the picture attached below.

def alternating_list(lst1, lst2):

   lst3 = []

   for x in range(len(lst1)):

       lst3.append(lst1[x])

       try:

           lst3.append(lst2[x])

       except:

           pass

   if len(lst2) > len(lst1):

       lst3.extend(lst2[len(lst1):])

   return lst3

def reverse_alternating(lst1, lst2):

   lst3 = []

   if len(lst1) == len(lst2):

       for x in range(len(lst1) - 1, -1, -1):

           lst3.append(lst1[x])

           lst3.append(lst2[x])

   return lst3

def alternating_list_no_extra(lst1, lst2):

   lst3 = []

   max = 0

   if len(lst1) > len(lst2):

       max = len(lst2)

   else:

       max = len(lst1)

   for x in range(max):

       lst3.append(lst1[x])

       try:

           lst3.append(lst2[x])

       except:

           pass

   return lst3
