The answer to this is the apostrophe is missing, and so is the question mark. There are no tricks in the letters, which I will show below.

Did you know that 80% of UCSD students could not find the error above? Repost this with the title “what’s wrong here”, and when you click “post “, the answer will be really obvious.

Letters are represented by different numbers in a computer;  Not normal numbers but hexadecimal representation. The letters start with A being represented by 65 in decimal, or 41 in hex. Knowing this, we know that if there is any trickery such as using the number zero for the letter O, or using \ / instead of the letter V, it will come up in the hex dump. Any nonsequential number signifies a deviation from the pattern, and the trick.The following is the AAA->ZZZ part of the hex dump. Note the following:

• 0a is the newline character
• When reading, remember to read from right to left for each chunk below. If you wanted the combination ABCD, you would read it BA DC
• Since this is hex, 49 is not followed by 50, but rather 4a (then 4b, 4c, up to 4f, then 50). Use the google calculator above if you need help

0000010 0a0a 4141 0a41 4242 0a42 4343 0a43 4444
0000020 0a44 4545 0a45 4646 0a46 4747 0a47 4848
0000030 0a48 4949 0a49 4a4a 0a4a 4b4b 0a4b 4c4c
0000040 0a4c 4d4d 0a4d 4e4e 0a4e 4f4f 0a4f 5050
0000050 0a50 5151 0a51 5252 0a52 5353 0a53 5454
0000060 0a54 5555 0a55 5656 0a56 5757 0a57 5858
0000070 0a58 5959 0a59 5a5a 0a5a

The above has been clipped from the entire message. Here we can see without a doubt, that the letters are sequential right from 41 to 5a, or A to Z with no surprises such as \/ (5c 2f) instead of V.

Also note, the letter L in lower case is 6c. 6c does not appear where one would expect to see i, which is 49.

Other possibilities include finding things such as KKK. While the KKK is wrong, I don’t think this is the point of this exercise.

Please can we put the constant questions to rest?
