WebOct 6, 2009 · Be careful, though, these add some other things to the complexity that you may not consider (for instance, Counting Sort and Radix sort both add in factors that are based on the size of the numbers you're sorting, O (n+k) where k is the size of largest number for Counting Sort, for instance). WebSep 13, 2009 · It has the time complexity of O (n log n) on average case run and O (n2) on worst case scenario. But Quicksort is generally considered to be faster than some of sorting algorithms which possess a time complexity of O (n log n) in average case.
