hi

I am just rigting a mere logic i am not writing a code. please adjust with me as am ina hurry to move out of my office.
I know u would be smart enough to make it into a working model

just try this way a reverse hash

Instead of the linenumber as has and elements in the array reverse this concept u will find a simple solution. Just build a hastable with ur elements as key and their line numbers as hash tabls. This would solve your problem.


Please let me know your comments on it.

Thanks
Sasi Kumar
