=(1/1-1/2)+(1/2-1/3)+(1/3-1/4)+.+(1/n-1/(n+1))
=1-1/(n+1)
=n/(n+1)
我也不知道,不好意思
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+1+1+1+1+1+1+1+2+5+4+8+3+6+2+1+4等于多少?
