If we use PARTITION, instead of RAMDOMIZED_PARTITION, in the randomized select algorithm, what are the run-time complexities for the best case and the worst case

The device responsible for performing the fetch-execute cycle is the CPU.

Explanation:

The fetch execution cycle is the way or method the CPU executes instructions given to it. In this process or cycle, the CPU fetches the instruction, then decodes it, executes it, and stores the information in its database.

The CPU executes one instruction at a time.
