6+9+7+8
6*8/(9-7)=24
8*(6/(9-7))(8*6)/(9-7)8/((9-7)/6)(8/(9-7))*66*(8/(9-7))(6*8)/(9-7)6/((9-7)/8)(6/(9-7))*8
8÷(9-7)*6=24
下面结果是我的程序利用穷举方法运行出来的结果:5、6、7、8:((5-6)/8)-7 = 24(5+(7-8))*6 = 24((5+7)-8)*6 = 24((5+7-8)*6) = 24(5+7)*(8-6) = 24((5*7)/8)*6 = 24((5*7/8)*6) = 24((5-8)+7)*6 = 24((5-8+7)*6) = 24(5-(8-7))*6 = 24(5-(8/7))*6 = 24((5-8/7)*
有两种算法,举例如下:8*6÷(9-7)=24
1: 6 * (8 ÷ (9 - 7))2: 6 * 8 ÷(9 - 7)3: (6 * 8) ÷ (9 - 7)4: (6 ÷ (9 - 7)) * 85: 6 ÷ (9 - 7) * 86: 6 ÷ ((9 - 7) ÷ 8) 7: (8 ÷ (1 + 1)) * 68: 8 ÷ (1 + 1) * 69: 8 ÷ ((1 + 1) ÷ 6)10: 8 * (6 ÷ (1 + 1))11: 8 * 6 ÷(1 + 1)12: (8 * 6) ÷ (1 + 1)不改变无解
