WebMerge Sort is one of the most respected sorting algorithms, with a worst-case time complexity of O (nlogn). Merge sort works by dividing the array repeatedly to make several single-element arrays. The concept of merge sort involves breaking down an array of n elements into n individual elements. WebThe average case time complexity of Tim sort is O(n log n). Worst Case Complexity - It occurs when the array elements are required to be sorted in reverse order. That means suppose you have to sort the array elements in ascending order, but its elements are in descending order. The worst-case time complexity of Tim sort is O(n log n). 2. Space ...
