If the picked no. is from 1 to 60 then A is executed otherwise B is executed. An example of 10 tickets picked by Scheduler may look like this - Ticket number - 73 82 23 45 32 87 49 39 12 09. Resulting Schedule - B B A A A B A A A A. A is executed 7 times and B is executed 3 times.Jun 02, 2021 · Mollnn - 博客园. 2021年2月6日.
