25. (FOR HIGH LEVEL 5) THINK ABOUT EASIER QUESTION.

I think this knack is a kind of secret. When you can’t get the meaning of the problem, you should think about “easier question”.

Here is a sample question.

“Continuous 500 times? It’s crazy. Hmm… I can get nothing. OK, let’s think about the case in continuous 5 times.” Then you will get something or hints.

See you next.
