Web1 Answer. Sorted by: 6. The first iteration will do will do n − 1 comparisons, the next n − 2, the second n − 3 and so on. In total n − 1 iterations are done. Hence, you need to find the sum of ( n − 1) + ( n − 2) +... + 1 which is ( ( n − 1) 2 + n − 1) / 2 which still is O ( n 2). So the optimization does not improve the ... WebFeb 26, 2016 · Optimizing selection sort is a little silly. It has awful best-case, average, and worst-case time complexity, so if you want a remotely optimized sort you would (almost?) always pick another sort. Even insertion sort tends to be faster and it's hardly much more complicated to implement.

Dart Sorting Algorithms: Bubble Sort by Utsav Dutta Medium
In pseudocode the algorithm can be expressed as (0-based array): The bubble sort algorithm can be optimized by observing that the n-th pass finds the n-th largest element and puts it into its final place. So, the inner loop can avoid looking at the last n − 1 items when running for the n-th time: More generally, it can happen that more than one element is placed in their final position on a sin… Web21 minutes ago · I have heard that merge sort is faster than Selection, Insertion or Bubble sort, yet, it exceeds time limit while other sorts don't at the same platforms. Here is the code: #include #include using namespace std; void Merge (vector& nums, int s, int e) { int mid = (s+e)/2; int i=s,j=mid+1, MainIndex=s; vectorMerge ...
