主要实现购买电子卡、详单查询、账单查询、充值缴费功能，是在Windows环境下用QT编写的。

在一个圆形操场的四周摆放着n 堆石子。现要将石子有次序地合并成一堆。规定每次只能选相邻的2 堆石子合并成新的一堆，并将新的一堆石子数记为该次合并的得分。试设计一个算法，计算出将n堆石子合并成一堆的最小得分和最大得分。 (Playground in a circle around the stones are placed n heap. Stone is to have the order to merge into a pile. Provisions can only choose 2 adjacent stones piled into a heap of new and new pile of stones a few in mind for its combined score. Try to design an algorithm to calculate the n heap into a pile of stones the minimum scores and maximum scores.)
