Recursive Append (30 points). On RecursiveAppend.java write a recursive method appendNTimes that receives two arguments, a string and an integer. The method appendNTimes returns the original string appended to the original string n times.
Use the following method header:public static String appendNTimes (String original, int n)
Examples:
appendNTimes(“cat”, 0) returns “cat”
appendNTimes(“cat”, 1) returns “catcat”
appendNTimes(“cat”, 2) returns “catcatcat”
The following restrictions apply to method appendNTimes:
YOUR CODE MUST BE RECURSIVE
Do not use loops (while, do/while, or for).
Your code must return a string without extra space, comma or any other character that is not in the original string
You may write your own main method to test your appendNTimes method. Autolab will ignore your main method.
