HOTELS - Hotels Along the Croatian Coast

There are N hotels along the beautiful Adriatic coast. Each hotel has its value in Euros.

Sroljo has won M Euros on the lottery. Now he wants to buy a sequence of consecutive hotels, such that the sum of the values of these consecutive hotels is as great as possible - but not greater than M.

You are to calculate this greatest possible total value.


In the first line of the input there are integers N and M (1 ≤ N ≤ 300 000, 1 ≤ M < 231).

In the next line there are N natural numbers less than 106, representing the hotel values in the order they lie along the coast.


Print the required number (it will be greater than 0 in all of the test data).

50th in spoj ..AC in 1 go...nice problem

There is nothing to memoize here. Solution is O(n) , you don't need any algorithm to solve this one.

Do we have to consider negative numbers?

done using variation of KADANAE'S algorithm simple and easy

Amazing problem. But time limit is too strict. Got a TLE in Python but an AC in C++14 :D
