Filter redux

[dunbarx at aol.com]

Again, thanks everyone. I am pretty good at munching data. I missed a syntax construct.


I play scrabble seriously. Driving home from work each day I amuse myself by taking the three letter combinations from passing license plates and making words with minimum chars. So if I see "rbd", I know I can make "bard" or "brad", both better than "beard". If I see "cwm" I know I need do nothing, since that is already a word.


Yesterday I saw "czk". I knew "zincked", and wondered what it would take to write a program to find all words that contain those three letters. With the "filter command now working, it takes three lines of code, plus four more for input/output of the data.


I love LC.

Filter works on lines. From the docs: "Filters each line in a container, 
removing the lines that do or don't match a pattern."

What were you hoping to get?
