-----------------------------------------------------------
i think two ways solve this issue:
1).Add judgment about if {{-yn}} * {{-ys}} < {{-p}} system.exit(1) and Print
message: {{-yn}} * {{-ys}} shoule more than the {{-p}}
2).Create taskManager with one solt until {{-yn}} * {{-ys}} >= {{-p}} as
default
maybe 1) is more friendly to users
