        count=0;
        for(fen5=money/5;fen5>=1;fen5--){
            for (fen2=money/2;fen2>=1;fen2--){
                for (fen1=money;fen1>=1;fen1--){
                    if(fen1+2*fen2+5*fen5==money){
                    printf("fen5:%d, fen2:%d, fen1:%d, total:%d\n",fen5, fen2, fen1, fen5+fen2+fen1);
                    count++;                       
                    }}}}
