Write a function that returns the intersection of two vectors using the following header:

The intersection of two vectors contains the common elements that appear in both vectors. For example, the intersection of two vectors {2, 3, 1, 5} and {3, 4, 5} is {3, 5}. Write a test program that prompts the user to enter two vectors, each with five strings, and displays their intersection. Here is a sample run:

Enter five strings for vector 1: Atlanta Dallas Chicago Boston Denver PEnter Enter five strings for vector2: Dallas Tampa Miami Boston Richmond Enter The common strings are Dallas Boston
