Oh yeah, Martin: The halfsorted is calculated by the formula: (A random number between 0 and 500) - (a random number between 0 and 450) Thanks for your replies by the way. They really helped! --~--~-~--~~~---~--~~ You received this message because you are subscrib

I calculated times taken to calculate a variety of n values with the bubble, selection and quick sort. I know that the bubble, selection are both O(n^2) sorts and that the Quicksort is O(nlogn). But how could I predict the time taken for these sorts when I know n? here is my table for the bubble

Well actually, let me recorrect my question: I calculated times taken to calculate a variety of n values with the bubble, selection and quick sort. I know that the bubble, selection are both O(n^2) sorts and that the Quicksort is O(nlogn). But how could I predict the time taken for these sorts whe

I know how the complexity of an algorithms is calculated, but how would this relate to the time it takes? Let's say I have 25000 random numbers I'd like to sort with the selection sort. Now how could I use Big O notation to calculate the time taken to sort these numbers?? I mean I understand it's
