情景解说
A B C D E F G H I J K L ，12个人， A储值了一笔钱，A邀请B和C储值了一笔钱，A从B和C获利他们充值金额的10%，即为邀请所得；然后，B又邀请D、F、G充值了一笔钱，B又分别从D F G那里分别获得一份邀请所得金额；这时，C 也邀请了 H I 冲值了一笔钱，C 即获得了两笔邀请所得；最后，G又邀请了J充值了一笔钱，获得一份邀请所得，I 又邀请了K L充值了一笔钱，获得两份邀请所得。
规则说明
自己邀请所得的金额，全额归自己；而自己发展的下线，可以从所有下线的每笔邀请所得，获利百分之十；到了下线的下线，也就是第三级，自己可以从下线的下线的每笔邀请所得，获利百分之一。
计算要求
统计这12个人，每个人最终的获利金额，以及自己从多少人身上获利。
