# Desc: Take two lists, say for example these two:
#           a = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89]
#           b = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]
#       and write a program that returns a list that contains only the elements
#       that are common between the lists (without duplicates).
#       Make sure your program works on two lists of different sizes.
#   Extras:
#       1. Randomly generate two lists to test this

list_a = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89]
list_b = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]

common_list = []

for i in list_a:
    if i in list_b:
        if i not in common_list:
            common_list.append(i)

print(common_list)
