Given an array, how do you efficiently find out the minimum xor pair. I've written a short blog discussing the idea behind it.

To help you solidify the concepts discussed, I've created 1 + 1 practice problems. You can access them here: https://codeforces.net/group/7Dn3ObOpau/contest/503551

https://cfstep.com/training/tutorials/bitwise-operations/xor-is-minimized-for-adjacent-sorted-elements/

The problems are untested. If you see any issues, please let me know.

If you need any help or hints for the practice problem, you can ask on my Discord Server. In case you are interested, you can also checkout my youtube channel
