Write a method called append that accepts two integer arrays as parameters and returns a new array that contains the result of appending the second array’s values at the end of the first array. For example, if arrays list1 and list2 store [ 2, 4, 6 ] and [ 1, 2, 3, 4, 5 ] respectively, the call of append(list1, list2) should return a new array containing [ 2, 4, 6, 1, 2, 3, 4, 5 ] . If the call instead had been append(list2, list1) , the method would return an array containing [ 1, 2, 3, 4, 5, 2, 4, 6 ].
