Questions: do you always need to have m or can you just use a helper method where you get the number of elements in a, that way you limit the number of parameters you pass always?

1. More on list intersections

Algorithm: commonElementsList( a, m, b, n)
Input: Two arrays, a and b, with m and n distinct String elements respectively
Output: A list of String elements common to both arrays

function commonElementsList( a, m, b, n) {
	if( listIntersection( a, m, b, n ) > 0 )
