Then you can merge a 2 and 1 long list with at most another 1+2-1 = 2 comparisons, yielding a 2 and 3 long list. Finally you merge these lists with at most 2+3-1 = 4 comparisons. So I guess the answer is 8.

Web62. Under what case of Master’s theorem will the recurrence relation of merge sort fall? a) 1 b) 2 c) 3 d) It cannot be solved using master’s theorem Answer: b Explanation: The recurrence relation of merge sort is given by T(n) = 2T(n/2) + O(n). So we can observe that c = Logba so it will fall under case 2 of master’s theorem. 63. WebDec 3, 2024 · Merge sort involves recursively splitting the array into 2 parts, sorting and finally merging them.
