Problem:
Score : 200 points

Problem Statement

A ball will bounce along a number line, making N + 1 bounces. It will make the first bounce at coordinate D_1 = 0, and the i-th bounce (2 \leq i \leq N+1) at coordinate D_i = D_{i-1} + L_{i-1}.

How many times will the ball make a bounce where the coordinate is at most X?

Constraints

1 \leq N \leq 100

1 \leq L_i \leq 100

1 \leq X \leq 10000

All values in input are integers.

Input

Input is given from Standard Input in the following format:

N X
L_1 L_2 ... L_{N-1} L_N

Output

Print the number of times the ball will make a bounce where the coordinate is at most X.

Sample Input 1

3 6
3 4 5

Sample Output 1

2

The ball will make a bounce at the coordinates 0, 3, 7 and 12, among which two are less than or equal to 6.

Sample Input 2

4 9
3 3 3 3

Sample Output 2

4

The ball will make a bounce at the coordinates 0, 3, 6, 9 and 12, among which four are less than or equal to 9.

Solution in C# (Mono 4.6.2.0) (judge verdict: Accepted)

using System;

public class Hello
{
	public static void Main()
	{
		string[] line = Console.ReadLine().Trim().Split(' ');
		var n = int.Parse(line[0]);
		var x = int.Parse(line[1]);
		line = Console.ReadLine().Trim().Split(' ');
		var L = Array.ConvertAll(line, int.Parse);
		var p = 0;
		var a = 0;
		while (p < n)
		{
			a += L[p];
			if (a > x) { Console.WriteLine(p + 1); goto end; }
			p++;
		}
		Console.WriteLine(n + 1);
	end:;
