I've got a flag, but I can't submit it. What's wrong? Should I change words order in brackets {}? Help me please. You can write me in discord redlineo#0307.

Neat challenge but I would've rated it a light medium. For people struggling with this, just look up what an XOR cipher is and do some arithmetic
