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 Bounding 
{
    public static void Main(string[] args)
    {
        string[] input = Console.ReadLine().Split(new string[]{" "}, StringSplitOptions.RemoveEmptyEntries);
        int N = Int32.Parse(input[0]);
        int X = Int32.Parse(input[1]);
        input = Console.ReadLine().Split(new string[]{" "}, StringSplitOptions.RemoveEmptyEntries);
        int[] L = new int[N];
        // 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++) 
        {
            L[i] = Int32.Parse(input[i]);
        }
        for (int i = 0; i < N; i++)
        {
            D = D + L[i];
            if (D > X)  break;
            count++;
        }
        Console.WriteLine(count);
    }
