There's no automatic function that does this for you, as far as I know.
To do this properly yourself, you'll need a three (or is it only two?)
step process:

1. Compare the sizes
2. and 3. Iterate over the lists and compare the objects in them one by one, thereby effectively comparing the order of the lists and the exact content.

hi,

Thanks for your reply.
I feel that this process is an expensive one.Sothat only i asked for any
other solution.
Once again thanks for that.

Do you have any evidence for that feeling though? It's absolutely
crucial for performance work that you find out just how much something
is costing before you try to improve it. Otherwise, you don't know
whether you've made an improvement or even whether you *need* to
improve it.
