Number of Subarrays with xor K | Brute - Better - Optimal

Description

Problem Link: https://bit.ly/3jLfElm

Notes/C++/Java/Python codes: https://takeuforward.org/data-structure/count-the-number-of-subarrays-with-given-xor-k/

We have solved the problem, and we have gone from brute force and ended with the most optimal solution. Every approach's code has been written in the video itself. Also, we have covered the algorithm with intuition.
