Need help in proving: Codeforces Round 882 (Div. 2), C. Vampiric Powers, anyone?

In this problem. I'm trying to prove that at the end of the array, you can only achieve xor of any subarray of the original array . I'm unable to do so and the proof given in the editorial is also unclear. Can someone prove it? Thanks

Tags help, proof, bitwise-xor
