🎭 Happy Primes Checker

📜 Overview

This project classifies numbers as:

• Happy Prime: A prime number that is also a happy number.
• Sad Prime: A prime number that is not a happy number.
• Happy Non-Prime: A non-prime number that is happy.
• Sad Non-Prime: A non-prime number that is not happy.

🎯 Features

• Checks for Primality: Determines if a number is prime.
• Happy or Sad Classification: Uses an iterative approach to classify numbers.
• Continuous Input Mode: Users can check multiple numbers.

A Happy Number follows this rule:

1. Take a number and replace it with the sum of the squares of its digits.
2. Repeat this process.
3. If it eventually reaches 1, the number is happy.
4. If it enters a loop (not reaching 1), it is sad.

🧮 Example Calculations

• 19 (Happy Prime) 1² + 9² = 82 8² + 2² = 68 6² + 8² = 100 1² + 0² + 0² = 1 ✅ (Happy)

• 17 (Sad Prime) 1² + 7² = 50 5² + 0² = 25 2² + 5² = 29 2² + 9² = 85 8² + 5² = 89 🔄 (Loops infinitely) ❌ (Sad)
