Give recurrence for quick sort algorithm runtime when it sorts n-randomly sorted

integers. Derive the closed form solution using sum-method.

Company ABC is dealing with big data and they want to compress data because one of the most crucial steps for the Company is towards efficient data protection, lossless and speedy transfer over the network at less cost So your main job being an ML Engineer is to choose a compression technique from available two options (Fixed Length vs Variable-Length) given to you by the Company. Keep in mind all the important parameters while deciding about a compression.
