Java Int to String | HackerRank

 You are given an integer , you have to convert it into a string.

Please complete the partially completed code in the editor. If your code successfully converts  into a string  the code will print "Good job". Otherwise it will print "Wrong answer".

 can range between  to  inclusive.

Sample Input 0
