You got AC, where is the problem?

Two easy tips, do not use split, use StringTokenizer. You also do not need to allocate array a.

I consider those as micro enhancements if you are using basic optimizations, it should be ok and you have to make your code quicker by implementing better algorithm…

Yes i have got the ac but the time was 8.39 which was quite large.but i have tried it without array and time has reduced to 8.20.

I also want to know that how we can take large inputs in java…in jan15 long contest my solution was accepted for one subtask but it was not for another subtask with larger set even after i have used long instead of int.

is there any other way out to take large inputs please suggest!! thanks!
