As a human, you have no problem answering this question, as long as the list is reasonably short. Vassilis Athitsos. University of Texas at . Arlington. 1. Bits and . Radixes. Every binary object is defined as a sequence of bits.. In many cases, the order in which we want to sort is identical to the alphabetical order of binary strings.. Selection Sort. Insertion Sort. Merge Sort. Quick Sort. Bubble Sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in wrong order.. Worst and Average Case Time Complexity: . Outline The bucket sort makes assumptions about the data being sorted Consequently, we can achieve better than Q ( n ln( n )) run times We will look at: a supporting example the algorithm run times (no best-, worst-, or average-cases) Bucket & Radix Sorts Efficient Sorts QuickSort : O( nlogn ) – O(n 2 ) MergeSort : O( nlogn ) Coincidence?
