Hey BMDan,

Apologies...for the same..

To clear your doubts..
1. It is not the performance i am worryin about
2. I am trying to reduce the number of comparisons as both the files contain the same data
3. if file a and b have 4 lines each we would be having 16 comparisons...but since file a and b are similar... there would comparisons like line1 = line3 and also line 3 = line1 .. we may have a single comparison rather than both as line1=line3 or line3=line1 both are the same..

Do let me know if there is any way I can implement this...

Thanks and Regards
Kaushik
