Why not: String.Join(" ", words) ?
Saves all the hassle with StringBuilder etc.
I agree. The StringBuilder code could be replaced with: Array.Reverse(words); return String.Join(" ", words); However, every response to this question I've seen (admittedly only three or four so far) used StringBuilder. When I ask, "why not use Join?" most C# programmers seem to respond that StringBuilder is "faster" (I haven't measured the difference in performance). To be fair to C#, I'm not a C# expert and haven't asked this question (yet;-) in a public C# forum but StringBuilder seems the "natural" approach of practising C# programmers. Perhaps most practicing Java programmers would similarly reach straight for the StringBuffer hammer? It would be interesting to pose this problem to a Java expert (which is not me). Given their similarities, I would expect a Java and C# solution to this problem to look fairly similar. Cheers, /-\ Send instant messages to your online friends http://au.messenger.yahoo.com
