Q2. Time Complexity of Merge Sort
Ans. 
Merge Sort has a time complexity of O(n log n).
• Merge Sort is a divide-and-conquer algorithm that recursively divides the array into two halves.

• It then merges the sorted halves to produce a sorted array.

• The time complexity of Merge Sort is O(n log n), where n is the number of elements in the array.

• This makes Merge Sort efficient for sorting large arrays.

• Example: Sorting an array of 8 elements would require 3 merge steps...read more
