(2*3*4*5)*(1/2+1/3+1/4+1/5)=
(2*3*4*5)*(1/2+1/3+1/4+1/5)=
(2*3*4*5)*(1/2+1/3+1/4+1/5)=
120*(1/2+1/3+1/4+1/5)=60+40+30+24=154
(-2/3)+1/2+4/5+(-1/2)+(-1/3)
1 2 3 4 5 1 2
1+1+2+2+3+4+5
(1+1/2+1/3+1/4+1/5)*(1/3+1/4+1)-(1+1/3+1/4)*(1/2+1/3+1/4+1/5)
matlab 编程数组的数据如下:8 1 1 1 1 1 1 3 3 2 1 1 5 1 1 3 1 1 2 1 1 5 3 3 3 1 1 4 5 1 1 1 1 1 2 2 2 2 4 3 1 5 4 2 1 1 1 2 1 3 1 1 2 2 5 2 1 3 2 5 1 1 3 1 1 1 1 2 1 5 4 2 2 1 3 4 1 2 3 1 2 4 4 1 1 1 2 2 2 2 2 1 1 4 4 1 3 2 1 1 5 1 1 3 7 1 1
(1+1/2+1/3+1/40)*(1/2+1/3+1/4+1/5)-(1+1/2+1/3+1/4+1/5)*(1/2+1/3+1/4)(1+1/2+1/3+1/4)*(1/2+1/3+1/4+1/5)-(1+1/2+1/3+1/4+1/5)*(1/2+1/3+1/4),不好意思,是下面这个!
