WebT (n) = T (n/2) + O (1) The algorithm divides the array in half at each step, and performs a constant amount of work to check the middle element. Therefore, the time complexity of the algorithm is O (log n). the assumption of a sorted array is crucial for the correctness of the algorithm. If the array is not sorted, we would need to spend O (n ... WebThe main function in the algorithm, merge_sort(), is the divide-and-conquer part of the algorithm, which splits the input list into halves and recursively sorts each half. The … WebQuicksort¶.
