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.

#include<vector>
#include<algorithm>
#include <iostream>
using namespace std;

int main()
{
	int n, x;
	cin >> n >> x;
	vector<int> vec(n);
	for (int i = 0; i < n; i++) {
		cin >> vec.at(i);
	}
	int l = 0;
	int count = 1;

	for (int i = 0; i < n; i++) {
		l += vec.at(i);
		if (l > x)
			break;
		else
			count++;
	}
	cout << count << endl;
