Merge Sort has a worst-case time complexity of O(nlogn), while Quick Sort has an average case time complexity of O(nlogn).

- Ans.
Compute amount of water trapped in an elevation map after raining
Iterate through the array and find the maximum height on the left and right of each bar
Calculate the amount of water that can be trapped on each bar using the difference between the minimum of the two maximum heights and the height of the bar
Add up the amount of water trapped on each bar to get the total amount of water trapped
- Q6. Zigzag traversal of a given binary tree.

Use sorted() function with lambda function to sort by key or value.
For ascending order, use reverse=False and for descending order, use reverse=True.
Example: sorted_dict = sorted(dictionary.items(), key=lambda x: x[0], reverse=True)
