Problem: Square every digit of a number and concatenate them.
Example:
- 9119 → 811181 (since 9²=81, 1²=1, 1²=1, 9²=81 → "81"+"1"+"1"+"81")
- 765 → 493625 (49-36-25)

My Solution:

def square_every_digit(num):
    num_str = str(num)
    result = ""
    for digit in num_str:
        squared = int(digit) ** 2
        result += str(squared)
    return int(result)

AI's Solution (via ChatGPT):

def square_every_digit(num):
    squared_digits = ''.join(str(int(digit) ** 2) for digit in str(num))
    return int(squared_digits)

💡 Key Takeaway:
The AI uses join() with a generator expression to simplify the loop, making the code shorter and more "Pythonic". Both methods work, but join() is cleaner for string concatenation!
