I think everybody must be having same problem in Problem D having time limit exceeded on Test case 15. The time limit is too strict for the problem. I am tired of optimizing it further now and I have seen exactly same logic being accepted. I am tired and frustrated now. Somebody pls tell how to optimize it from here on.
Here is my Code:

Just few modifications in your code and it passed in 1044ms.

I see so declaring a map do the job. Yeah I thought of that then I just ignored that diff will be not so much in worst case.
Can anyone guide me how I can optimize this code. Luckily it just got accepted (Time : 1996 ms).

Small optimization of your code.
Also applying sieve in O(n) will help.
