Read the description below VERY carefully. Some clarifications have been added.

- One line with your first name.
- One line with your last name. If your last name is less than 2 characters long (highly unlikely), pad with blanks (before the newline).
- One line with your student ID.
- One line with a series of 32 0's and 1's corresponding to four 8-bit
bytes containing the ACSII
encoding (with the most significant bit set to 0 as ASCII is only
a 7 bit code) of a string (not in the C sense, so don't add a
'\0' at the end) formed by (from left to right):
- the first letter of your first name,
- the blank space ' ' character,
- the first two letters of your last name (possibly padded with blanks if not long enough).

- One line with an integer (N) denoting the total (original + check bits) number of bits needed for a Hamming encoding of the 32 bits.
- A line with a series of (N) 0's and 1's corresponding to the
Hamming encoding of the 32 bits. The bits are numbered from left
to right (as in class, NOT as in Forouzan !)
123456...

When putting the data bits in between the check bits, you should start with the lowest bits first. So, the 32bits 011...10011 should appear in the appropriate places of the Hamming encoding in the order 1, 1, 0, 0, 1, ..., 1, 1, 0. (Note that this allows you to use the description in Forouzan's book and reverse the result to get exactly the line you need here). - A line with a series of 16 0's and 1's corresponding to the CRC-16 checksum for the 4-byte data.
- A line with a series of 48 0's and 1's corresponding to
the original data, followed by the CRC-16, subsequently
garbled by inverting 18bits, starting from the 9th bit (counting
up from the left; the first bit on the left has number 1 so the 9th
bit is the first one of the second byte).
Note that the above line previously read
``CRC-16 checksum'' meaning ``Cyclic Redundancy Check sum''.
It is one of many different types of
checksums. It is
**not**what you find in section 9.6. - One line with the remainder (series of 16 0's and 1's) after division of the above by the CRC-16 generator polynomial. Obviously, if the remainder is 0000000000000000, the error went undetected.
- One line with your first name.
- One line with your last name.

If your first or last name contains spaces (blanks), that is acceptable (as long as you encode correctly).

Letters may be lower case or upper case (or mixed) as long as they are encoded with the correct ASCII code.
