    In this assignment, you will complete several number-related challenges inspired by computer hardware concepts.
    It reviews the following concepts:
      - Variables
      - ASCII table, chars, type casting
      - Strings, ints, doubles
      - Console input/output
      - Arithmetic operators (+, -, *, /, %, Math methods)
    
    DO NOT use:
      - Methods
      - Conditionals (if, switch)
      - Loops (for, while)
      - Arrays

    Follow the instructions and complete each part by writing your code where indicated.
    Add comments to explain your calculations.

        // Part 1: ASCII Art from Hardware Codes
        // --------------------------
        // Use ASCII values to display "CPU" on one line with spaces.
        // Example of type casting with ASCII:
        // int code = 65; 
        // char letter = (char) code; // letter will store 'A'
        // System.out.println(letter);

        // Write your code here:


        // --------------------------
        // Part 2: Algorithms with Modulus
        // --------------------------
        // Suppose a memory address is stored as a 5-digit number: 12345
        // Print the last digit using the modulus operator (%).
        // Example: 
        // int number = 12345; 
        // int lastDigit = number % 10; // extracts the last digit
        // System.out.println(lastDigit);

        // Then, calculate and print the sum of all digits.
        // Do it manually using arithmetic operators without loops.
        
        // Write your code here:


        // --------------------------
        // Part 3: Integer Overflow Experiment
        // --------------------------
        // Create an int with value Integer.MAX_VALUE (2147483647).
        // Add 10 to it and print the result.

        // Write your code here:

        // --------------------------
        // Part 4: Round-Off Error in Floating-Point Arithmetic
        // --------------------------
        // Divide 10.0 by 3.0 and then multiply the result by 3.0.
        // Print the result and observe if it equals 10.0.
        // Example of floating-point error:
        // double value = 10.0 / 3.0;
        // double result = value * 3.0;
        // System.out.println(result); // Compare with 10.0

        // --------------------------
        // Convert binary "1101" to decimal manually using arithmetic operations.
        // Example: Binary 1101 = (1x2^3) + (1x2^2) + (0x2^1) + (1x2^0)
        // Use Math.pow(base, exponent) for powers.
        
        // Convert hexadecimal "1A" to decimal manually.
        // Example: Hexadecimal 1A = (1x16^1) + (10x16^0)
        // Remember, 'A' in hex is 10 in decimal.
