Hello everyone, I wrote this problem and it had overwhelmingly negative replies in my solution among with 8 resolved reports. Even though that reports are resolved and my answer remains unchanged, it is somehow not enough to convince them. I had to delete my solution to remove the bandwagon effect. Personally I think this problem is wonderful yet it saddens me that many people would disagree with the answer and move on without learn anything. I tried my best to explain the solution, but I am such terrible at explaining.
So now my problem has no solution, even though it has 3,418 solvers (15%) at the time of writing...
So, I would greatly appreciate it if you come and check my problem, and post solution if you can solve it. The more solutions, the better.
