is equivalent to running
yum install MariaDB But for MARIADB, the direct installation of MARIADB is not going to run as a service, because you only install MARIADB client, so you also need to download a series of MARIADB components than Mariadb-server (server side). Workaround: Run the yum Search all MariaDB A series of packages are then listed Mariadb-bench

First, how to determine whether a linked list has a ring:
Set two pointers (fast and slow). The initial values all point to the header. Slow moves one step forward each time, and fast moves two steps forward each time. If the linked list has a ring, fast must first enter the ring, when slow enters the ring, the two pointers must meet each other. (Of course, if the first line to the end of fast is null, It is a loop-free linked list)

The title is as follows: The existing array length is n+1, which contains 1 to n-2, the order is uncertain, of which two numbers appeared two times, now to find out the two digits.
Example A={2, 3, 1, 4, 5, 2, 4}, this array length is 7, storing 1 to 5, but 2 and 4 appear two times, program output 2 and 4.
Method 1 Brute Force search
Main idea: For the number of I in the array, look for all the integers i+1 to the end, a number if it occurs two time
