Answer:
list1 = [1, 2, 3]
list2 = [4, 5, 6]
list3 = []
newlist = []
for i in list1:
for j in list2:
if list1.index(i) == list2.index(j):
newlist.append(j)
newlist.append(i)
break
for i in reversed(newlist):
list3.append(i)
print(list3)
Explanation:
The programming language used is python.
List 1 and 2 are initialized, and two empty lists are initialized too, these two lists are going to be used in generating the new list.
Two FOR loops are used for both list one and two respectively, to iterate through their content, the IF statement and the break is placed within the for loop to ensure that there is no repetition.
The index of list 1 and list 2 are appended (added) to a new list one at a time.
The new list is then reversed and its content are added to list 3 to give the final solution.
NOTE: The reason a separate list was created was because the reversed() function does not return a list, so in order to get the list, it must be added to an empty list as you reverse it.
