(7)最特殊的是(6,9,9,10),9*10/6+9=24,9是3的倍数,10是2的倍数,两数相乘的积才能整除6,再也找不出第二个类似的只能用此法解决的题目了。
试一试,你也是算24的专家了。
(1,3,4,6)(1,4,5,6)(1,5,5,5)(1,5,J,J)
(1,6,6,8)(1,6,J,K)(1,2,7,7)(1,7,K,K)
(1,8,Q,Q)(2,2,J,J)(2,2,K,K)(2,3,5,Q).
(2,3,7,Q)(2,3,J,J)(2,3,K,K)(2,4,7,Q)
(2,4,10,10)(2,5,5,10)(2,7,7,10)(3,3,7,7)
(3,3,8,8)(3,5,7,K)(3,6,6,J)(3,7,9,K)
(3,8,8,10)(4,4,7,7)(4,4,10,10)(4,5,8,K)
(4,7,J,K)(4,8,8,J)(4,8,8,K)(4,10,10,J)
(5,5,7,J)(5,7,7,J)(5,5,8,J)(5,8,9,K)
(5,9,10,J)(5,10,10,J)(5,10,10,K)(5,J,Q,Q)
(6,6,6,J)(6,6,7,J)(6,6,9,K)(6,10,10,K)
(6,J,J,Q)(6,Q,Q,K)(8,8,8,J)(8,8,8,Q)
(8,8,9,Q)(8,J,Q,Q)(9,10,J,K)(9,J,Q,Q)
(10,Q,Q,Q)
算24一般掌握以下方法
1、最常见的算法是3*8,4*6,2*12,所以最先考虑的应该是上述3种算法。
