字符串组合高效算法竞彩项目中，对选择的多组比赛进行组合过关和赛果组合拆分。

这是一个对字符串组合算法的示例，使用选号标记移位算法和笛卡尔积进行计算，避免使用递归，效率极高。-String combination efficient algorithm SMG project, the selection of multiple race combinations clearance and Results combination splits.

This is an example of the string combination algorithm, using random selection algorithm and the Cartesian product marked shift calculations, avoid the use of recursion, and very efficient.
