any idea of printing by using Queue?
I am using levl ordr trversal to print..
since this seems to print by using Array, doesn't it?

hmm, the algorithm you gave was quite helping
But how about if the 'c' are random integers (i.e. they are not only from 1-5)?

Thank you

I have already edited my question above, hope you have better understanding about my problem. Thanks -)
