What is the difference between a list, array, and stack?

Problem Statement

What is the difference between a list, array, and stack?

Step-by-Step Explanation

Lists, arrays, and stacks are data structures with different storage rules and access patterns.

1. Identify what the question is asking. In Data Structures, this usually means naming the known quantities, the unknown quantity, and the concept that connects them.
2. Write the relevant definition, rule, or relationship before substituting numbers or manipulating symbols.
3. Work one step at a time and keep units, signs, and restrictions visible.
4. Check whether the answer makes sense in the original context.

Final Answer

Lists, arrays, and stacks are data structures with different storage rules and access patterns. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
