1、任意输入三个0—9数字进行自身加后，求得它们的平均数(本程序实现的是求商运算，余数不考虑)

2、输入使用者的幸运数字，实现自身相加后与任给的俩个数乘积比较，进行俩种结果的图形输出，若前者小于后者，输出图形“E”，否则输出一个直角三角形

-1, any input three numbers after their 0-9 plus, and seek their average (this program is to seek quotient and the remainder do not consider) 2, enter the user' s lucky numbers, and summed to realize their own Given any two of the product of the number of comparison, the results were two kinds of graphical output, if the former is smaller than the latter, output pattern " E" , otherwise, outputs a right triangle
