Ok guys. I went thru' what I wrote all day today and I sound like an arrogant know-it-all, don't I ? :-) I didn't write anything incorrect but the way I did was surely wrong. Shit happens in life and it was just one of those days when u feel like shouting at everybody. I will post the answer in a few days [ I have it right here . The problem is that the answer is too long to type and my digicam is out of order ]. My sincere apologies to Nirman, Dada, shree5, PRESIDINGEARTHLY, newuser. Have fun and I will try to fix up things in my life.
