The values in the array is a consecutive Numbers

Time：10-09

Such arrays [" F8 ", "F6", "F4", "F3", "F2", "B1" and "B3"].
Need to request a letter after the array is adjacent Numbers, if not need to add the letters + adjacent Numbers on
For instance should deal with the above array into: [" F8 ", "F7", "F6", "F5", "F4", "F3", "F2", "F1", "B1", "B2", "B3"].

CodePudding user response:

F1 and neighbouring B1? This is the number of floors? There are other letters?
