[Tutor] Simple guessing game - need help with the math

[Derek Jenkins]

I am a newbie (please correct me if I am wrong), but I happen to think
that it would be best to suggest that your input be in the same case
as that of your variables. In other words, it appears that you are
suggesting the user make an input choice of H, L, or C while the
program appears to want to handle the variables h, l, or c.

Clearly my statements do not directly relate to math, but I do not see
how your program would be able to handle the input of H, L, or C.
