Problem Statement for "Billboard"

Problem Statement

An electronic billboard is supposed to display large letters by using several lightbulbs per letter. Given a message, and how each enlarged letter looks as a 5x5 arrangement of lightbulbs, return the enlarged message.

The enlarged representation of the letters will be in a String[] with each element formatted as follows (quotes added for clarity):

"<letter>:*****-*****-*****-*****-*****"

Where <letter> is a single uppercase letter [A-Z], and each * is either the character '#' (representing a lit lightbulb) or a period ('.') (representing an unlit lightbulb). Each group of 5 (delimited by a dash, '-') represents a row in the 5x5 representation of the letter. So, "T:#####-..#..-..#..-..#..-..#.." means that the 5x5 representation of 'T' is: 

"#####"
"..#.."
"..#.."
"..#.."
"..#.."

Return the enlarged message as a 5-element String[], with each element representing one row of lightbulbs (where element 0 is the top row). Leave 1 (one) column of periods ('.') between each adjacent pair of letters in the enlarged message.
