Derive merge sort time complexity

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). WebJan 13, 2024 · The complexity of the entire algorithm is the sum of the complexity of two steps which is .
