Go语言视频零基础入门到精通

我爱java

C语言趣味程序百例精解之java实现（44）分数之和：

程序：public class Test44{
    public static void main(String args[]){
      int s,count=0;
      System.out.printf("The 4 fractions which sum is equal 1 are:\n");
       for(int p=2;p<5;p++)
        for(int q=p;q<7;q++)
          for(int r=q;r<13;r++)
           if(p*q*r-q*r-p*r-p*q!=0){
              s=(p*q*r)/(p*q*r-q*r-p*r-p*q);
              if(((p*q*r)%(p*q*r-q*r-p*r-p*q)==0)&&s>=r)
                 System.out.printf("[%2d] 1/%d+1/%d+1/%d+1/%d=1\n",++count,p,q,r,s);
            }
     }
}运行结果：
