QR code in today is quite popular, making two-dimensional code is not difficult, there are many Web sites to make two-dimensional code, input information, immediately converted to two-dimensional code. However, it is not so easy to make a

text of the Markov chain algorithm will first show your, and then randomly remove flowcharts or table two words, assuming that the choice is flowcharts, then the new prefix is your flowcharts, similarly, select Table, The new prefix is your table, with the new prefix your flowcharts, and then select its suffix again, which is randomly selected in and and will, repeating the process to produce a readable text. The detailed description is as follows: Copy
