[Toplanguage topic discussion] Today we are thinking
By Liu weipeng
Recently, I have read many books on psychology and thinking, some books on mathematics and problem solving, and I have made some questions. The two combined and made some thoughts. It was originally written to maillist, but some thoughts and summaries that have been written since this time have come out, beyond the normal length of a mail, so I posted it.
Polia's "how to solve it"

So I checked each loop carefully and tried several times, the problem was finally discovered by me. It turned out to be "I" in a loop, incorrectly written as "j". At

However, today I have changed my mind. First, it takes a lot of time and effort to add a complex image in manual programming, and it is not conducive to intuit
