🛠️ Issue (Number)
Closes #2042
Description
In the Armstrong Number Checker project, when I focus on the input field and press backspace (with either no input or just one digit), it shows a browser alert saying “Invalid input.” This alert appears unnecessarily during normal text deletion.
Expected behavior
The alert should not appear when the user is just deleting input (especially if it's empty or partially entered). Validation should only happen when there's actual input to evaluate.
