Write a function @lowupp(info)@ that expects to receive a string; if it starts with the character @"^"@, then it returns the rest of the string in upper case; if it starts with the character @"_"@, then it returns the rest of the string in lower case; if it starts anyhow else, it returns the string unchanged.
The function counts 100 points
>>> lowupp("_Hi There!") hi there! >>> lowupp("^Hi There!") HI THERE! >>> lowupp("Hi There!") Hi There!
