人机对弈，互取火柴。取最后一根者输。每次至少取一根，最多取4跟。如果人先取则人必输。如果机先取，则机器等待人出错。否则人胜。-Human-computer game, and take matches. The last one loses. Check at least one of each, with up to 4 check. If the person is who will get lost. If the machine to check, then wait for others to machine error. Otherwise, people win.

说明：  条码仓库管理系统，特别适合中小型超市，解决了库存、入库、出库、库存查询、数据报表等大量人工需要完成的事情，现在只需要轻轻的点几下鼠标就能完成，大量节约了人力和物力，实现了无纸化的操作，能把出库入库报表打印出来或导出为excel，更加直观和省时。(Bar code warehouse management system, especially suitable for small and medium-sized supermarkets, has solved a large number of manual tasks such as inventory, warehousing, warehousing, inventory query, data report forms and so on. Now it can be accomplished with a few clicks of the mouse. It saves a lot of manpower and material resources, realizes paperless operation, and can print out or export the warehouse report forms into excel, which is more intuitive and more intuitive. Time saving.)
