Horizontal scaling involves adding more machines to distribute load, while vertical scaling involves increasing resources on a single machine.
Horizontal scaling is more cost-effective as it allows for adding cheaper machines as needed.
Vertical scaling is limited by the capacity of a single machine and can be more expensive.
Examples of horizontal scaling include adding more servers to a web application cluster.

Transform a sequence into a non-decreasing order using minimum adjacent additions.
Identify positions where the sequence decreases.
Each decrease indicates a necessary operation to merge elements.
Example: For [3, 2, 5], merge 3 and 2 to get [5, 5] (1 operation).
Count total decreases to determine the number of operations needed.
Example: For [1, 3, 2, 4], merge 3 and 2 to get [1, 5, 4] (1 operation), then merge 5 and 4 to ...
