Php is arranged in the order of 1, 2, 3, or 4, 5. if there is a string of numbers 1, 2, 3, 7, 8, how can we divide 123 into a group, let's divide 7, 8 into another group, namely, separating 1, 2,
Output an M * n matrix arranged according to the following rules.1 6 72 5 83 4 9
Analysis: The key is to find out the matrix rules. on the Internet, the analysis is as follows:
Set behavior I, column J
1 2 M 2 m + 1 4 M 4 m + 1 6 m ..
2 m + M-
this time, the third and fourth disks are idle. When B data is written to the third Disk in a certain band, and B data is checked in the fourth disk, in this way, both data a and data B can be read and written at the same time.
VII. Raid 6
Raid 6 adds a verification area on the basis of RAID 5, each of which has two verification areas. They use an unused verification algorithm to improve data reliability.
Next we will introduce several types of com

Three points:
1. Do not write system. Out. Print () as system. Out. println.
2. If the operation is performed on the diagonal line, use if to determine.
3. Generally, two-tier loops control the number of rows in the outer loop. External Loop variables m
