Write a method that accepts an array 'nums'. Return a new array with one less element than 'nums' and containing the products of all the adjacent elements in 'nums'. For example, if 'nums' contained {4,3,100} you would return {12,300} because 4*3=12 and 3*100=300. Note that 'nums' will have at least one element in it. If 'nums' only has one element, you will return an empty array. Look at the test data for examples. You may use one or more helper methods. Remember to make sure each method has only one return statement.
