Handle Invalid Number Format

Read one line of input and parse it to an int with int.Parse, then print Number: <n>. If the text is not a valid integer, int.Parse throws a FormatException — catch it and print exactly Not a number. Use top-level statements with try/catch.

Input 42 prints: Number: 42
Input abc prints: Not a number

Expected Output:

Number: 42
