回复:能讲一下分析过程吗?[:)]
There are 3 kinds of symbols, *, _, and blank, and the *'s and _'s always form groups of five with a single or double blanks in between. I had ruled out the possibility of each group represents a word (that would be beyond my ability to decode them anyway), and since a 5 digit binary number can go up to 31, so I had a hunch that each group represents a different letter. When I got the 1st word “look”, I knew I got it right. (if the mapping rule is a little more complicated than simple sequential correspondence, I would probably give up after a few trials. )
