2 Factorial
Problem Statement
Calculate the Factorial of a Positive Number Using Recursion.
The factorial of a non-negative integer N, denoted as N!, is the product of all positive integers less than or equal to N. The factorial of 0 is defined as 1.
Here is what the example input/output looks like:
| Input | Expected Output | Explanation |
|---|---|---|
| Number = 5 | Factorial = 120 | The factorial of 5 is calculated as 5 _ 4 _ 3 _ 2 _ 1 = 120. |
| Number = 7 | Factorial = 5040 | The factorial of 7 is calculated as 7 _ 6 _ 5 _ 4 _ 3 _ 2 _ 1 = 5040. |
| Number = 1 | Factorial = 1 | The factorial of 1 is 1 itself. |

🎨 Explain it visually
Build the mental picture, not memorization.
I just read a lesson on **2 Factorial** (DSA) and want to truly understand it. Explain 2 Factorial from first principles using ONE vivid real-world analogy and a visual mental model — draw it as ASCII art or a clear step-by-step diagram — with a concrete example using real numbers. Then ask me one question to check I got the mental picture, and wait for my reply. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
🤔 Walk me through it (interactive)
Socratic — adapts to where you're stuck.
Teach me **2 Factorial** interactively. Ask me ONE guiding question at a time, wait for my answer, and adapt to my confusion — build the idea with me step by step instead of explaining it all at once. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
🧪 Quiz me & fix my gaps
Active recall exposes what you missed.
Quiz me on **2 Factorial** with 5 questions, easy to tricky, ONE at a time. Tell me if each answer is right; at the end, explain clearly what I got wrong and why. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
🧠 Make it stick
Intuition + hook + flashcards for long-term memory.
Help me remember **2 Factorial** for the long term: give the one-sentence intuition, a memorable hook/mnemonic, a tiny worked example, and 3 active-recall flashcards (Q -> A). If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
