Answer in C++ only order for Jon to win and be noticed by his favourite streamer Daenerys, he decides to donate a significant amount of money. Every gift given to Daenerys is at least 11 bestcoins and is displayed in Daenerys' stream next to any message written and visible to any viewer. After Daenerys noticed that she had set a goal of at least XX bestcoins for the streaming day, all of her viewers only donated amounts below XX bestcoins. Jon decided to upgrade them all by directly donating more than or equal to XX beastcoins. Next, he decides to write a message along with his special gift to leave her in awe. His message would be: "Crossing my gift with any other gift will only increase the value of my gift". By crossing, he means to take XOR. But for all his intellectual brilliance, money doesn't grow on trees for Jon. After all, he is an underpaid employee in his fictional big name MNC. Unlike the cash cow Daenerys who makes videos of how she carelessly donated to other people, Jon…
