What is a linked list?

Problem Statement

What is a linked list?

Step-by-Step Explanation

A linked list stores data in nodes that point to the next node instead of using one continuous block of memory.

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

A linked list stores data in nodes that point to the next node instead of using one continuous block of memory. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
