Subarray with XOR less than k
Given an array of n numbers and a number k. You have to write a program to find the number of subarrays with xor less than k.
Examples:
Input: arr[] = {8, 9, 10, 11, 12}, k=3 Output: 4 Sub-arrays [1:3], [2:3], [2:5], [4:5] have xor values 2, 1, 0, 1 respectively.
Input: arr[] = {12, 4, 6, 8, 21}, k=8 Output: 4
