Worst case of Quicksort algorithm?
The worst case occurs when data is already sorted where the complexity is O(n^2) instead of the well known O(n log n)
Which is faster among quicksortmergesort?
quicksort
What is the difference between best worst and average case complexity of an algorithm?
These are terms given to the various scenarios which can be encountered by an algorithm. The best case scenario for an algorithm is the arrangement of data for which this algorithm performs best. Take a binary search for example. The best case scenario for this search is that the target value is at the very center of the data you're searching. So the best case time complexity for this would be O(1). The worst case scenario, on the other hand, describes the absolute worst set of input for a given algorithm. Let's look at a quicksort, which can perform terribly if you always choose the smallest or largest element of a sublist for the pivot value. This will cause quicksort to degenerate to O(n2). Discounting the best and worst cases, we usually want to look at the average performance of an algorithm. These are the cases for which the algorithm performs "normally."
What is quicksort?
Quicksort is a popular algorithm to sort items in software, aiming at completion in the smallest number of steps (shortest time) possible.

What cables give you the best HD performance?
HDMI cables give you the best HD performance
How does the sorting algorithm Quicksort work?
Quicksort is faster than other algorithms, though it is a comparison sort, not a stable sort. It uses O(n log n) comparisons to sort n terms. It works well with cache.
