OAO SVM classification

首先由计算机产生[1,100]之间的随机整数，然后由用户猜测所产生的随机数。根据用户猜测的情况给出不同提示，如猜测的数大于产生的数，则显示“High”，小于则显示“Low”，等于则显示“You won”，同时退出游戏。用户最多可以猜7次。(First produced by the computer [1100] between a random integer, then by the user to guess generated random numbers. According to the user guesses are different tips, such as guess the number is greater than the number, then displays " High"," Low", smaller than the display to show " You won", at the same time to quit the game. The user can have up to7 guess.)
