因为数据差距实在太大，从10-10000都有，要是全搞决策树我估计我是啥都不用搞了，看着电脑卡死就ok！所以特地将连续的数据转化为连续的数据！看看是不是会生成新的、更好地决策树！

废话不多说！直接丢代码！不然真是难受的一批！写了好一会儿才搞定的！

改善之后的属性为：

为此还特地写了个C++的程序来观察！

#include
    
     #include
     
      #include
      
       using namespace std;int main(){    string line[72];    int count=0;    for (int i = 0; i < 72; ++i)    {        cin>>line[i];    }    for (int i = 0; i < 24; ++i)    {        cout<<"[->"<
       <<": "<
        
         <<" --> "<
         
          <<" --> "<
          
           <
          
         
        
      
     
    

最后整出来还蛮好看！?
