if my choices are correct/make sense/ like for a randomized array, it is sorted fastest using mergesort reverse is fastest with bubble...

use merge here because bubble sort will take more steps

Of your choices, merge sort is by far the best. Quicksort is probably the other major alternative to have a look at. A cool one for arrays with only a small range of possible numbers is counting sort: http://en.wikipedia.org/wiki/Counting_sort

Merge sort and Randomised Quicksort have running times of O(n lg n). Bubble sort and Selection sort is O(n^2) Now O(n lg n) is faster than O( n^2), for a large enough n. Hence, Merge sort and Quicksort beats Bubble and Selection sort. Also, Counting sort has linear running time O(n). So, that's even better that O(n lg n), but it's complex and a little hard to understand.

the url above tells me randomized > merge sort revese > shell sort nearly sorted>insertion sort duplicates > quick sort, but insertion works quite good as well.
