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;
using System.Collections.Generic;
public class ABC130B {
    public static void Main() {
        int N, X, D = 0, ans = 0;
        List<int> L = new List<int>();
        string[] str = System.Console.ReadLine().Split(' ');
        N = int.Parse(str[0]);
        X = int.Parse(str[1]);
        str = System.Console.ReadLine().Split(' ');
        for (int i = 0; i < N; i++) {
            L.Add(int.Parse(str[i]));
        }
        int j = 0;
        while (D <= X) {
            ans++;
            if (j == L.Count) break;
            D += L[j];
            j++;
        }

        System.Console.WriteLine(ans);
    }
