Game of XOR Java

PROGRAM TO FIND XOR OF ALL SUBARRAY XORs







public class MAIN {

         

    // Returns XOR of all subarray xors

    static int getTotalXorOfSubarrayXors(

                          int arr[], int N)

    {

         

        // initialize result by

        // 0 as (a xor 0 = a)

        int res = 0;

         

        // select the starting element

        for (int i = 0; i < N; i++)

         

            // select the eNding element

            for (int j = i; j < N; j++)

         

            // Do XOR of elements

            // in current subarray

            for (int k = i; k <= j; k++)

                res = res ^ arr[k];

     

        return res;

    }

     

    // Driver code

    public static void main(String args[])

    {

        int arr[] = {3, 5, 2, 4, 6};

        int N = arr.length;

         

        System.out.println(

            getTotalXorOfSubarrayXors(arr, N));
