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.
Input
In the first line of the input there are integers N and M (1 ≤ N ≤ 300 000, 1 ≤ M < 2^{31}).
In the next line there are N natural numbers less than 10^{6}, representing the hotel values in the order they lie along the coast.
Output
Print the required number (it will be greater than 0 in all of the test data).
Example
input5 12 2 1 3 4 5output 12 
input4 9 7 3 5 6output 8

Come on SPOJ, tle in java but AC in CPP. So, many times this happened to me.

rolling pointer, AC in one go ! :))

AC in one GO..!! O(N) Two pointers

No searching on google for a algorithm , instead think and you will get one , was getting WA Because was adding sum again in each cycle , please see that you can use previous sum of hotel price , instead of calculating it again from scratch in each cycle.

ALIENS = CODEFURY =HOTELS(without considering number of hotels just focus on max sum)

A/C in one go! No algorithm needed, simple two pointer technique. :)

Thought it was a little annoying dealing with single hotels that might cost more than the cost limit. Try:
