The operation of processing each element in the list is known as ……a.sortingb.mergingc.insertingd.traversal

Step 1: Break Down the Problem

We need to identify the correct term that describes the operation of processing each element in a list. The options provided are:

1. Sorting
2. Merging
3. Inserting
4. Traversal

Step 2: Relevant Concepts

Let's define each of the terms in the context of list operations:

1. Sorting - This is the process of arranging the elements of a list in a certain order (e.g., ascending or descending).
2. Merging - This refers to combining two or more lists into a single list.
3. Inserting - Involves adding a new element into a specific position within the list.
4. Traversal - This is the act of accessing each element in the list, typically for processing them (reading, modifying).

Step 3: Analysis and Detail

• Sorting involves arranging, not processing.
• Merging implies combining lists but does not specify processing.
• Inserting focuses on adding elements rather than processing existing ones.
• Traversal explicitly means going through each item in the list to perform some action.

Step 4: Verify and Summarize

Given the definitions and analysis, the term that most accurately fits the description of processing each element in a list is traversal.

Final Answer

The correct answer is d. traversal.
