Talented Code Challenge

• Path following algorithm in ASCII Map
• Find the position of character '@'
• Follow the path, stop when character 'x' is reached

Code Challenge

Write a piece of code that takes ASCII map as an input and outputs the letters and the path that algorithm travelled.

• Input:
  • ASCII map
• Output:
  • Collected letters
  • Path as characters

Map 1

  @---A---+
          |
  x-B-+   C
      |   |
      +---+

Expected result:

• Letters ACB
• Path as characters @---A---+|C|+---+|+-B-x

Map 2

  @
  | C----+
  A |    |
  +---B--+
    |      x
    |      |
    +---D--+

Expected result:

• Letters ABCD
• Path as characters @|A+---B--+|+----C|-||+---D--+|x

Map 3

  @---+
      B
K-----|--A
|     |  |
|  +--E  |
|  |     |
+--E--Ex C
   |     |
   +--F--+

Expected result:

• Letters BEEFCAKE
• Path as characters @---+B||E--+|E|+--F--+|C|||A--|-----K|||+--E--Ex
