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.

using System;

namespace B
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] input = Console.ReadLine().Split();
            int N = int.Parse(input[0]);
            int X = int.Parse(input[1]);
            int[] L = Console.ReadLine().Split().Select(i => int.Parse(i)).ToArray();
            // 1回目の跳ねを考慮して初期化
            int D, count;
            D = 0;
            count = 1;
            for (int i = 0; i < N; i++)
            {
                D += L[i];
                if (D > X) break;
                count++;
            }
            Console.WriteLine(count);
        }
    }
