Re^2: Perl confusion

[stamp1982]

Scot, Thanks for your message. I did not want a solution to the problem but a breakdown of what was expected in a beginners terms. I know to obtain user input I have to use STDIN but how to write that obtain that with the whitespace is where my confusion lies and I would appreciate some explanation. It is not my homework just practicing Perl for beginners. Please what does the sequence length mean? Thanks
