Question

Java

Write a function/method called

CheckHash: takes two arguments, an array and an integer count n. The function computes the exclusive OR of the hashcodes (https://docs.oracle.com/javase/8/docs/api/java/lang/String.html#hashCode--) of the first n strings in the array (result type int).

Answer 1

public class HashCodes {

    public static int CheckHash(String[] arr, int n) {
        int result = 0;
        for(int i = 0; i < arr.length; ++i) {
            result = result ^ arr[i].hashCode();
        }
        return result;
    }

    public static void main(String[] args) {
        String[] arr = {"Hello", "How", "are", "you?"};
        System.out.println(CheckHash(arr, arr.length));
    }

}
