A Rubik's Cube Solver

Copyright (C) 2018 Hideyuki Kawabata

Here is a solver based on the CFOP method without F2L.

Usage:

• with GHCi:

  (a) input: a scramble

   *Cubing> solve_check "R  L'  U'  D2  F2  U'  F'  R  D'  U'  B2"
   ...
  

  (b) input: a scrambled pattern

   *Cubing> solve_check_pat "OBOWBWYW, BRWYBOWW, ROROWRYG, BBYBGORY, GROBGGOY, RRYGGYWG"
   ...
  

  Note: the above input string corresponds to the following pattern (based on the Western color scheme):

         YWB                            765         
         WWW                            8W4         
         OBO                            123         
     OGG WOB YRW ROG                765 765 765 765 
     YGB WRY GBO YOB       <--->    8G4 8R4 8B4 8O4 
     GRO BRW ROR BBY                123 123 123 123 
         WYG                            765
