>leaves out what we need to work with the problem
Can you include the numbers and letters we need to use?

Answer 2

@poopsiedoodle that's my problem actually, "aplhanumeric codes" it includes numbers from 0-9 and letters a-z right?

Answer 3

@poopsiedoodle it is not specified in the book what numbers or letters to use, it just simply tells 'alphanumeric codes'

Answer 4

I guess, but your question looks like something that included an image file or something with the numbers and letters you were supposed to use.

Answer 5

Oh. Well, there are a ton of possibilities then...

Answer 6

@Compassionate

Answer 7

@poopsiedoodle it doesnt have an image or something, just a question haha :)) so do we have 36 alphanumberic codes? :)) 26 letters and 10 numbers??

Answer 8

Doubt it. If the last digit has to be odd, and each code is four digits, it's prolly not gonna be just 36.

Answer 9

I'm not exactly sure how to do this though :(

Answer 10

no, what i mean is that, from the question itself, it requires 36 alphanumeric codes, not the answer as 36 :)

Answer 11

I'm quite confused then.
