WebLet’s solve the recurrence of merge sort: This was the recurrence of the merge sort algorithm: Comparing with the standard form of the Master method mentioned earlier, here, a = 2, b = 2, and d = 1. So, Case 1 is the solution for the merge sort algorithm. So, the time complexity of the merge sort algorithm is O (nlog (n)). WebInteger[] aux = new Integer[a.length]; merge(a, aux, 0, 3, 7); You will find the number of compares is $7= 8-1$. Here is a fact about general situations. (Number of compares) Let …
