@stoking: We independently came to very similar solutions. @Hallicon, I just
did this last week; so this solution passes the unit tests. I like naming the
variables in a way that explains their logic; this eliminates the need for
comments. The if-expression is the procedure's final expression, which means
this procedure will return the string from the if-expression.
import strutils
proc hey*(s: string): string =
let strippedS = s.strip
let isQuestion = strippedS.endsWith("?")
let isYell = (strippedS == strippedS.toUpperAscii) and
(strippedS.find(UppercaseLetters) >= 0)
let isSilence = (len(strippedS) == 0)
if isYell and isQuestion:
"Calm down, I know what I'm doing!"
elif isYell:
"Whoa, chill out!"
elif isQuestion:
"Sure."
elif isSilence:
"Fine. Be that way!"
else:
"Whatever."
Run
