i'll search this in the newgroup, that's ok, i accept my mistake.
But it is not my assingment, i came across this question on internet,
tried to solve it, but couldn't get it. that's why i am asking, it will
be helpful if instead of pulling my leg, you could give me the link to
the solution.
thanks in advance, no hard feelings, :)
