Explanation:
1. Function Definition: The code defines a function called `check_number()` to encapsulate the logic.
2. Input Validation Loop:
- `while True:` creates an infinite loop until a valid number is entered.
- `try:` attempts to convert the user's input to an integer.
- `except ValueError:` handles cases where the user input is not an integer.
- `if 1 <= number <= 100:` checks if the number is within the range 1 to 100.
- If the input is valid, the loop `break`s.
3. Comparison and Output:
- `if number > 50:` checks if the number is greater than 50.
- `elif number < 50:` checks if the number is less than 50.
- `else:` handles the case where the number is equal to 50.
- An appropriate message is printed based on the comparison result.
4. Function Call: The `check_number()` function is called to execute the algorithm.
How it works:
The code first prompts the user to enter a number. It then validates the input to ensure it's an integer between 1 and 100. Once a valid number is obtained, it compares the number to 50 and prints the corresponding result (greater than, less than, or equal to 50).
