Model alphabet codes

Maps in Clojure are used to model key and value pairs.

  • Keys must be unique within a map.
  • A key can be a number, string or keyword.

Vectors in Clojure are a general data structure that are good for handing any kind of information.

Note Define a data structure where each letter of the alphabet is represented by a 6 digit binary code

Lets define a name called alphabet that is bound to a map. Each key in the map is a character of the alphabet and each value is a vector of numbers that represent a binary code.

The map also includes a binary code for a full stop and space character

  1. (def alphabet {"A" [0 1 0 0 0 1]
  2.                "B" [0 0 1 0 1 0]
  3.                "C" [0 1 0 0 1 0]
  4.                "D" [1 0 1 0 0 0]
  5.                "E" [1 0 1 1 0 0]
  6.                "F" [1 1 0 1 0 0]
  7.                "G" [1 0 0 1 1 0]
  8.                "H" [1 0 1 0 0 1]
  9.                "I" [1 1 1 0 0 0]
  10.                "J" [0 0 1 1 1 1]
  11.                "K" [0 1 0 1 0 1]
  12.                "L" [1 1 1 0 0 1]
  13.                "M" [1 1 1 0 1 1]
  14.                "N" [0 1 1 1 0 1]
  15.                "O" [1 1 0 1 1 0]
  16.                "P" [1 1 1 1 1 0]
  17.                "Q" [1 0 1 1 1 0]
  18.                "R" [1 1 1 1 0 0]
  19.                "S" [0 1 1 1 1 0]
  20.                "T" [1 0 0 1 1 1]
  21.                "U" [0 0 1 0 1 1]
  22.                "V" [0 1 1 0 0 1]
  23.                "W" [1 1 0 1 0 1]
  24.                "X" [1 0 1 0 1 0]
  25.                "Y" [1 0 0 0 1 1]
  26.                "Z" [1 1 0 0 1 1]
  27.                "." [1 0 1 1 0 1]
  28.                " " [0 0 1 0 0 0]})
