Problem Description
The program takes two lists and finds the intersection of the two lists.

Problem Solution
1. Define a function that accepts two lists and returns the intersection of them.
2. Declare two empty lists and initialize them to an empty list.
3. Consider a for loop to accept values for the two lists.
4. Take the number of elements in the list and store it in a variable.
5. Accept the values into the list using another for loop and insert into the list.
6. Repeat 4 and 5 for the second list also.
7. Find the intersection of the two lists.
8. Print the intersection.
9. Exit.
