What is the time complexity of the Merge operation in Merge Sort?

Step 1: Understand that Merge Sort is a sorting algorithm that divides an array into smaller parts.
Step 2: Recognize that the Merge operation is the process of combining two sorted arrays into one sorted array.
Step 3: Note that during the Merge operation, we look at each element of the two arrays to place them in the correct order.
Step 4: Realize that if we have two arrays of total length n, we will need to check each of the n elements once.
Step 5: Conclude that since we check each element once, the time it takes to complete the Merge operation is proportional to n.
Step 6: Therefore, the time complexity of the Merge operation in Merge Sort is O(n).
