Assume that the complexity of a divide-and-conquer sorting algorithm is given by: +c T(n): = if n>1 if n = 1 where 'e' is a constant. Solve this recurrent problem for T(n) and express the run-time complexity of the algorithm using Big-0 notation. 5.3 Algorithm analysis (2 marks) Give the complexities of these three algorithms. In particular, give the proof of the complexity of the MergeSort algorithm. Select Sort Insertion Sort Merge Sort Time complexity in Big O notation Step 1: Write the recurrence relation for merge sort: Step 2: Guess its complexity Step 3: Prove it using mathematical induction Figure 2: Proof of the complexity of the merge sort algorithm using the Substitution Method
