Hello,
I was wondering what the best way was for tranforming a list of
alphanumerical characters from main IO() such as:
Enter String:
A 101 E 182
and tranforming it into an Int list of
[0, 101, 4, 182]
Which converting A and E to 0 and 4 is easy enough with toEnum/fromEnum and
simple subtraction, and using read can convert to a [Char], but recognizing
101 as a single Int from a Char string in main, and getting both converted
together as part of the same function, I'm a bit less sure of without
resorting to much lower level imperative methods.
Thanks in advance and thank you for your time.
