Part 1: Your classmate Yurtle has a sticky keyboard and sometimes he presses down on a letter key for too long and so 'a' will be typed as 'aa' or 'aaaaa'. (For some reason the space bar and period keys work fine and all those characters he wants to keep.) Create a java íle with a class called 5tringHelper. In it write the method as described below. public static 5tring clean5tring(String input) Write a static recursive method that creates a "clean string" getting rid of any of the adjacent duplicate letters. Your method may not contain any for loops. (Adjacent means "next to each other") Examples: input: "wattteer in thhhhhhhheee Illakke" → output: "water in the lake" input: "egrreattt dayyy!!" → output: "great day!" input: "so.. whhhaaaat diiidd you sayy?" → output: "so. what did you say?" Hint: You will need to use the 5tring substring method. Part 2: Create a java file with a class name Recursive5ort. In it write an implementation of the recursive merge sort algorithm discussed in class. public static int] merge5ort(int] list) Hint: You may want to make a separate helper mergelint] a, into b) method that will merge two sorted arrays into one larger sorted array. A helper merge can contain a for loop. Hint: You may also find the Arrays copyOfRange function useful. It creates a copy of an array between two indexes. int] copiedArray = Arrays.copyOfRange(array, 0, 4);
