The third edition of the introduction to algorithms uses the insertion sort and merge order to learn about the running time of the program.
I use the post-class proof to demonstrate, how to use the mathematical induction method to prove the program run time of the merge sort.
On the implementation of merge sort, I have provided an almost perfect code in the previous article, the students need to learn from it.
The original question is as follows:
Using mathematical induction to prove tha

Each table item in the RIP route table provides certain information, including the destination address, the next hop address to the destination, and the measurement value. This metric value indicates the number of hops to the target terminal ). Other information can also be included. Router question supplement:

, capacity (minimum capacity HDD). 2 x 1T hard disks, composed of RAID 1and 1T capacity .C Security:RAID 1 with mirroring mode, so any one hard disk failure, the other corresponding hard disk has full data, you can continue to use, allowing 1 hard drives to be broken . D Performance:RAID 1 is only twice times faster when it is readable. Because you can read the same data from different hard disks, there is no speed added when you can write. E Use occasions: The most complete security combination
