Answer 1

So, do you have a programming question related to the above problem? I see you already have the solution.

Answer 2

Given a string, s, matching the regular expression [A-Za-z !,?._'@]+, split the string into tokens. We define a token to be one or more consecutive English alphabetic letters. Then, print the number of tokens, followed by each token on a new line.

Input formAT
A single string, s

s is composed of any of the following: English alphabetic letters, blank spaces, exclamation points (!), commas (,), question marks (?), periods (.), underscores (_), apostrophes ('), and at symbols (@).
Output Format

On the first line, print an integer, , denoting the number of tokens in string (they do not need to be unique). Next, print each of the tokens on a new line in the same order as they appear in input string .

Sample Input

He is a very very good boy, isn't he?

Sample Output

10
He
is
a
very
very
good
boy
isn
t
he
