黄金点游戏

黄金点游戏规则

 黄金点游戏是一个数字小游戏，其游戏规则是： 
N个同学（N通常大于10），每人写一个0~100之间的有理数 (不包括0或100)，交给裁判，裁判算出所有数字的平均值，然后乘以0.618（所谓黄金分割常数），得到G值。提交的数字最靠近G（取绝对值）的同学得到N分，离G最远的同学得到－2分，其他同学得0分。玩了几天以后，大家发现了一些很有意思的现象，比如黄金点在逐渐地往下移动。代码来自    http://blog.csdn.net/qq_32454537/article/details/78115826?locationNum=9&fps=1

用Java语言进行实现黄金点游戏，设置了进行用户名输入，然后用户逐个输入数字，然后自动计算出黄金点，自动给用户进行打分，并按用户顺序进行打分。
