WebAssume selection sort's goal is to sort in ascending order. Given list (9, 8, 7, 6, 5), how many swaps will occur during the first pass of the outer loop (i = 0)? 1 *One swap … WebAverage Case Time Complexity of Selection Sort. Based on the worst case and best case, we know that the number of comparisons will be the same for every case and hence, for average case as well, the number of comparisons will be constant. Number of comparisons = N * (N+1) / 2. Therefore, the time complexity will be O (N^2).
