Traditional hard drives are very slow to improve performance because of the limitations of their working principles. But the solid state hard disk price is expensive, in a short time is difficult to accept by the ordinary user. Therefore, the use of two or more pieces of hard disk to build a RAID disk array has become a more cost-effective hard disk performance i
Question: Given an array a[0,1,..., n-1], build an array b[0,1,..., n-1], where the element in B b[i]=a[0]*a[1]*.....*a[i-1]*a[i+1]*....*a[n-1].
Algorithmic thinking: The B[i] is regarded as the c[i]=a[0]*a[1]*.....*a[i-1],d[i]=a[i+1]*....*a[n-1 of the product of the two parts of C[i],d[i].

good, the other is not the capacity of the disk to make an effective use of the two methods mentioned are a combination of the first two, there are two groups of RAID0, a set of data storage, a set of data for the backup, Merging is RAID1, as shown in the following figure
1. RAID 5 (Balance of performance and data backup considerations)
It takes at least 3 or more disks in this structure to make up this type of disk
performance is also significantly enhanced.
Supported by RAID capabilities, AL-7121A's support for RAID is quite comprehensive, supporting not only the common raid levels of 0, 1, 3, 5,10, 6, 60,nraid, but also the current very popular JBOD to ensure that different enterprises, Different businesses offer a wide range of applications and performance-intensive st

Today in the QQ group chat to go language needs to improve the place, happy to spit a groove. I'd most like to change the syntax of the array-building slice, because the popular [start:end] approach is not rigorous at the moment. Later, when I did not remember which version, I introduced the three-segment [Start:end:max] syntax to create the slice. It's safe, but it's a lot uglier. As the following example shows, the definition of a two-segment will c
