Each letter of the alphabet has been assigned a different value from 1 to 26. The total values of the letters contained in a given word are as given below. Determine the value assigned to each letter of the alphabet.

BEG = 59            CALL = 48         CHIEF =  36           CRAZY =  60 
DEN = 53            GAME =  47        GUN = 51              HAM = 16
HAVE =  40          IF = 11           JACK = 24             KEY =  43
LAZE = 57           MAP =  28         MOVE = 58             NEON = 86
OXEN = 82           PALM = 47         QUIT = 40             QUITE = 60 
STALL = 80          TALK = 39         TORE = 73             VAST = 51
WALK = 54

*** Pen and Paper solution only.

From QUIT and QUITE, E=20.
From MAP and PALM, L=19.
Then from LAZE, AZ=18.
From CALL, AC=10.

With a few other observations, the program became reasonable in run time, as only n, a, k, m, g and f then needed to be run through all possibilities remaining after the used numbers were left, with the other letters being derived from these:
