Ruby Method of the Day - String.rjust
Signature
string.rjust(length) #=> new_string string.rjust(length, padding_string) #=> new_string
String.rjust is the counter justification method to
String.ljust.
string.rjust(length) right justifies string to the given length. If
length is greater than the length of string then a new string is returned
that is left padded to length with spaces, the default, or with
padding_string. If length is less than or equal to the length of string,
then string.rjust(length) returns a new string that is equal to string and
no padding or truncating occurs.
