Write a recursive method called that takes an integer and a string parameter. The integer parameter represents the depth of a folder inside a file structure and the string parameter represents the name of a file. The method should return a String constructed to represent the number of folders it takes to reach the specified file. If the integer parameter is 0 , the file exists at the current level and thus no folder structure is needed. For example: You are not allowed to construct any structured objects other than Strings (no array, ArrayList, StringBuilder, Scanner, etc) and you may not use a while loop, for loop or do/while loop to solve this problem; you must use recursion
