I took a program found in a textbook written by Deitel and Associates, provided several significant enhancements, and published it with their permission. Details available at link above.
I now have a Word Puzzle Pattern Matcher app at the Play Store.
I may have missed my calling. My personality is well-suited for conversing both with a computer in a limited techno-language and with a sense of humor with adolescents in the language of mathematics, which I did for 43 years.
Good for me.
I taught many of them how to think like a programmer and problem solver.
I have created two apps for Android devices, available at Google Play Store.
I also wrote a "Solitaire Scrabble" program capable of producing such as shown in the links below as well as a program that looks up words matching a pattern of letters, *s, ?s, and #s, screen shown at right below.
