Q1. Sort an array in O(nlogn)
Ans. 
Use merge sort algorithm to sort the array in O(nlogn) time complexity.
• Implement merge sort algorithm which divides the array into two halves, recursively sorts the halves, and then merges the sorted halves.

• Time complexity of merge sort is O(nlogn) where n is the number of elements in the array.

• Example: ['apple', 'banana', 'cherry', 'date'] can be sorted using merge sort in O(nlogn) time complexity.
