Hi Soroban,
By looking at ur reply, ur solution steps. I know that I've made a correct decision to join this forum, n perhaps, I should have join earlier.
I appreciate ur kind approach, n ur detailed solutions. Thanx a lot.
The way u solved it was exactly the way i tried before but didn't get it right. So I think, the min(x,y) not as easy as we thought...
Do u have some other solutions?
Im really glad that u've replied my thread. TQ very much n nice to know u.
