He tried to re-define your problem so that it can be easily translated to regular expressions:
Quote:
[beginning of string][whitespace] OR [whitespace](two or more) OR [whitespace][end of string]
He wanted you to write it out yourself. However, I will guide you to the solution. Using Peter's suggestion, you will get:
^\s OR \s{2,} OR \s$

In Perl, this may look like:
PERL
if ($str =~ /^\s/ || $str =~ /\s{2,}/ || $str =~ /\s$/) {
    print "String '$str' contains invalid white space sequence(s).";
}
