The basic principle is to randomly generate numbers using random:

1. Several characters to loop several times

2. Randomly generate a number that defines if the number is one of the values X, then randomly a 0-9 median number. Why 0-9, because 10 of the words accounted for two characters ....

3. In the loop, if the random number is not X, generate a number between 65-90, and then use the char () function to convert to the corresponding letter in the ASCII list, which is, of course, the uppercase A-Z, and then convert the uppercase Chen Xiao to write.

4. Add the generated characters to the list, and finally stitch the list into a string to O,
