I am not willing to write this blog because in many previous blogs i was flooded with downvotes but i will write because I need a help(I also do not have a friend which is proficient in java to whom i can discuss) from fellow coders in debugging which i am not able to find from last 2 hrs and 10 submission with 7RTE AND 24 AC every time.

I even use LONG , sort array of pairs even in equal case on the basis of index..still not able to figure out the reason of failure.
