New Challenge - Use string.Empty for validation

Closed this issue 2 years ago · 7 comments

String.Empty when compared will return true if it is null or an empty string ("")
Make a challenge returning a boolean value if the string passed in is equal to string.Empty

How is this different from challenge #45 Is the string empty?
