I suppose it all depends upon how many times you have to do it and how long the string is. I thought you were counting words -- what you are doing is counting characters? then the following is the easiest:
c = a.trim() + " " + b.trim() or c = (a[1][n]).trim() + " " + b.trim() There's not much advantage in doing the checks. Just trim and add.
