Hello All,

I have 2 arrays. I have written a script that searches each and every value of first array in the second array. Each & every value of Source Array should occur only once in the target array but it can occur anywhere.

If any of the source value doesn't occur or occur multiple times then the script reports to the user.

This script is working fine for small arrays.

But I tried executing the script for 2 arrays each of which containing 7,00,0000 elements and it is taking very long time.

I am using nested 'for' loops to make this search. How can I optimize it further to search source array in target array.
