Getting Map Coordinates

Instead of writing complicated HTML tables for every level, we'd like to use a simple string like levelMap to define new levels. But how?

The code in the editor transforms the string into an array of arrays. See for yourself by printing rows to the console.

Challenge

Print each of the coordinates in the map and the character at that coordinate. For example:

(1, 1): #
...
(4, 4): @

We'll use array mapping to do it.
