WebIn computer science, the time complexity of an algorithm is expressed in big O notation. Let's discuss some time complexities. O (1): This denotes the constant time. 0 (1) usually means that an algorithm will have constant time regardless of the input size. Hash Maps are perfect examples of constant time. O (log n): This denotes logarithmic time. WebBest Case Complexity: The merge sort algorithm has a best-case time complexity of O(n*log n) for the already sorted array. Average Case Complexity: The average-case time complexity for the merge sort algorithm is O(n*log n), which happens when 2 or more elements are jumbled, i.e., neither in the ascending order nor in the descending order.

WebJun 21, 2016 · Here are some key points of merge sort algorithm –. Merge Sort is a type of recursive algorithm. We can express time complexity of merge sort by this recurrence relation: T (n) = 2T (n/2) + O (n) Using Masters Theorem, we get -> T (n)=O (n*logn).
