Write a complete program to implement the link list operations as following.
a. Write a routine to make two lists L1 and L2 with 5 elements given by the user at run time. Or add two lists with its elements in the main function.
b. Write a routine to compute L1 ∩ L2 using only the basic list operations.
c. Print out L1, L2, and L1 ∩ L2.
For example if you have
L1 = {1, 3, 4, 6, 7}
L2 = {2, 5, 6, 7, 8}
So the
L1 ∩ L2 = {6, 7}
Note: You can use an empty list L3 to store the elements of L1 ∩ L2
