本演示程序演算约瑟夫环问题，人数n应为任意的，首先应输入一个值赋给初始报数上限m，程序应能自动保存出列人的序号和将出列的人所持的密码赋给m，再次作为报数上限，如此循环，直至所有人都出列为止。-The demo program Joseph Central calculus problem, the number n should be arbitrary, we must first enter a value assigned to the initial reported that the maximum number of m, the procedure should be able to automatically save a list of the serial number of people and held out the password given to m, again as reported maximum number of such cycles, until all that far out.

在自己的程序中完成SQK2K中的数据库的备份和恢复。虽然调用外部程序来完成，但是在自己的MEMO窗口中显示外部程序的字符界面输出。-in their procedures completed SQK2K the database backup and recovery. Although the call external procedures to be completed, but in their own MEMO window shows the characters external program interface output.

堆排序:思想: 用二叉树的结构来表示数组,及用数组来表示二叉树的结构,比如i为父节点其孩子为,2i,和2i+1.其中,大顶堆中 父节点大于其两个孩子 算法平均时间复杂度: O(nlogn) -HEAPSORT: thinking: using binary tree structure to express the array, and used to express an array of binary tree structure, such as i the parent node for its children, 2i, and 2i+ 1. Among them, the big top of a pile of the parent node greater than two children on average time complexity of algorithm: O (nlogn)
