Assist with following perl programming. This is all from chapter 8.

1. Using the pattern test program, make a pattern to match the string match. Try the program with the input string beforematchafter. Does the output show the three parts of the match in the right order?

2. Using the pattern test program, make a pattern that matches if any word (in the \w sense of word) ends with the letter a. Does it match wilma but not barney? Does it match Mrs. Wilma Flintstone? What about wilma&fred? Try it on the sample text file from the previous chapters exercises (and add these test strings if they werent already in there).

3. Modify the program from the previous exercise so that the word ending with the letter a is captured into memory $1. Update the code to display that variables contents in single quotes, something like $1 contains 'Wilma'.

4. Modify the program from the previous exercise to use named captures instead of relying on $1. Update the code to display that label name, something like 'word' contains 'Wilma'.

5. Extra credit exercise: modify the program from the previous exercise so that immediately following the word ending in a it will also capture up to five characters (if there are that many characters, of course) in a separate memory variable. Update the code to display both memory variables. For example, if the input string says I saw Wilma yesterday, the up-to-five characters are yest. If the input is I, Wilma!, the extra memory should have just one character. Does your pattern still match just plain wilma?

6. Write a new program (not the test program!) that prints out any input line ending with whitespace (other than just a newline). Put a marker character at the end of the output line so as to make the whitespace visible.
