Problem Statement

What is the difference between recursion and iteration?

Step-by-Step Explanation

Recursion solves a problem by calling itself, while iteration repeats steps with loops.

1. Identify what the question is asking. In Programming Basics, 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

Recursion solves a problem by calling itself, while iteration repeats steps with loops. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
