Hash files: Hash files use a technique called hashing. Hashing is a technique which provides quick access to record as in indexing but without the expense of index maintenance. In this technique storage is divided into many sections. These sections are called buckets. These buckets are capable of storing many records. These buckets are provided with bucket numbers. These numbers are used to identify buckets rather than keys in indexing.

7. See the code below and solve the following. public class Test { public static void main(String[] args) { int result = 0; } result = fn(2,3); System.out.println("The result is: + result); // fn(x, 1) = x // fn(x, y) = fn(x, y-1) + 2, when y>1 public static int fn(int x, int y) { if (x <= 1) return x; else return fn(x, y-1) + 2; } } 7-1. This program has a bug that leads to infinite recursion. Modify fn(int x, int y) method to fix the problem. (2 point) 7-2. Manually trace the recursive call, fn(2,3) and show the output (step by step). (2 point) 7-3. Can you identify the Base Case in recursive method fn(int x, int y)? (1 point)
