"Web13 okt. 2012 · why the time complexity of best case of top-down merge sort is in O (nlogn)? Because at each iteration you split the array into two sublists, and recursively invoke the algorithm. At best case you split it exactly to half, and thus you reduce the problem (of each recursive call) to half of the original problem. " - Merge sort time complexity best

Merge sort time complexity best

WebIn computer science, best, worst, and average cases of a given algorithm express what the resource usage is at least, at most and on average, respectively.Usually the resource being considered is running time, i.e. time complexity, but could also be memory or some other resource.Best case is the function which performs the minimum number of steps on … WebThat's way better than merge sort's overhead. Weaknesses: Slow in practice. While the asymptotic complexity of heap sort makes it look faster than quicksort, in real systems heap sort is often slower. (Remember, n and 2n are both, even though the ... So the best case time complexity is .
