Congrats on discovering and demonstrating that there's a 63% chance of success to hit X at least once, when p=1/N, in N tries, btw. No one really bothered to do the math on that one. You're definitely the first.
So then, if you're saying the prefix method is mathematically sound, right? Why are you giving it shit?
Because some people have an outsized ego, a need for attention, and any idea that doesn't come from them should simply be crushed no matter what.
The least they care about is math; all they care about is their need to stand out. They have multiple accounts for this. I don't know what they gain. I don't even look for puzzles, haha, and it's not like we're going to be rewarded here for sharing ideas.
That's why I apply the rule: I share ideas, I don't criticize anyone's ideas, I debate a bit with some haters for fun, and when I get bored, I put them back in the trunk and leave.
