/mnt/raid0mount /dev/nd0 /mnt/raid0 You can mount and use it,Use fdisk-L to view Mdadm-D/dev/md0 to View Details In this case, you should save the configuration information of RAID 0 in case of a fault. You can recover it next time, mdadm -D --scan /dev/md0 >> /etc/mdadm.conf You can use it directly next time. Mdadm-A -- Scan direct mounting How to detach RAID 0 should first detach the mount point of RAID 0, that is umount /mnt/raid0 Then use the command mdadm -S /dev/md0 Stop

the current step is x * num plus the sum of the numbers greater than itIn this way, it is easy to relate to the tree array. The number of reverse orders in the current step is actually the number larger than the previous one, at the same time, we can use a tree array to sum up the numbers greater than it. This solves the problem perfectly. At first, I saw that n was 10 ^ 5 times, and maybe I still had no experience, I think it may be super, so I made

print the files in the current directory, the magic happened, a demo.pyc file.Why is the PYc file for this Python file generated when a Python file is introduced? It can be argued that when a file is introduced, it is likely that the file will be referenced frequently, so Python compiles the file and generates bytecode. Instead of just executing a script, Python will assume that the script executes only once and that subsequent executions will not occur, so the PYc file is not generated for
