SPOJ Problem Set (classical)

9861. Hotels Along the Croatian Coast

Problem code: HOTELS

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).

I got so many wrong answers, but when I changed from ULL to int, everything was fine. Be careful!

A nice and tricky problem. Was making a small mistake which cost me 3 WAs.

Test cases seems not complete. If all the hotels added value is less than the required- the answer shud be the value of all hotels. But solution with value of n-1 hotels is gettting accepted.
