Solve the famous SEND MORE MONEY equation and other cryptarithmetic puzzles.
This program is written in Dr Racket, click me to install the latest version. You must be using Intermediate Student with lambda or Advanced Student to run the program.
To solve P1 (ON+ON+ON=GO), run the program and type in (solve P1 empty).
Solve your own puzzles from scratch by running (solve YOUR_PROBLEM empty).
See lines 14, 17 for how to format the problem.
You can also choose to solve a problem with a partial solution (ie a non-empty dictionary).
See lines 26, 35 and 39 on how to format a dictionary.
Don't try SEND MORE MONEY unless you have a lot of patience to wait for the code to finish running.
