Write a method countEvens that takes an ArrayList of String objects as input and returns the number of even length strings contained in the input. For example, if the input is ["one", "peach", "pear", "plum"] then countEvents(inp) should return 2. 2b) Write a method, mirror, that doubles the size of a list of integers by appending a mirror image of the list. For example, given an array list containing [1,5,2,6], the method should return an array list containing [1,5, 2, 6, 6, 2, 5, 1]. Use the ArrayList data structure to represent the input and output of this method
