打印“魔方阵”。所谓“魔方阵”是指这样的方阵，它的每一行、每一列和对角线之和均相等。例如，三阶魔方阵为: 8 1 6 3 5 7 4 9 2 要求打印出由1到n*n的自然数构成的魔方阵。-Print "magic matrices." The so-called "magic matrix" refers to the matrix, which each line, each diagonal out and the sum of all the same. For example, third-order magic Lineup : 8 1 6 3 5 7 4 9 2 request from a print n* n to the natural form of the magic number of matrices.

一个五维魔方的实现，该程序用C++实现了一个五维魔方。-The realization of a five-dimensional Rubik" s Cube

本游戏的主角是个小球，玩家通过按右键的时间长短来决定小球的初始速度，当按动左键时小球启动，小球在运动过程中将受到磨察力的作用，速度将减慢最终停止，小球停止的位置距离右边红色墙壁的距离（距离越近成绩越高）及小球在运行过程中与墙壁碰撞的次数（次数越多成绩越高）将决定玩家的最终成绩，按任意键程序将把当前成绩与存放在mc.txt中的历史成绩比较，给玩家以平价，并将当前成绩保存在mc.txt中。游戏有两个界面第一个界面是游戏场景，其中有三个参数，由左至右依次为“DIS”最终离右边墙的距离，“BUMP”小球在运行过程中碰墙的次数，“SPEED”小球的运行速度。第二个场景是成绩平价界面，根据玩家成绩给以相应的平价 。另外，由于机器配置的不同可能会出现速度上的迥异。-the protagonist of this game is a small ball, players adopted by the right to determine the length of time the ball"s initial velocity, when pressed button at the start of small ball, the ball movement in the process of grinding reviewer will be the role of power, speed will slow down eventually stopped, the ball stopped at a location away from the right side of the red walls of the distance ( the more recent results from the higher) and the ball in the course of operation and the number of collisions walls (the more the number of higher performance) will determine the ultimate success players by arbitrary procedures will bond with the current performance mc
