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.

import java.util.*;

    int n = sc.nextInt();
    int x = sc.nextInt();

    for (int i = 1; i <= n; i++) {
      l[i] = sc.nextInt();
    }

    int d1 = 0;
    int d2 = 0;
    int ans = 0;
    if (l[1] <= x) {
      for (int i = 2; i <= n + 1; i++) {
        ans++;
        d2 = d1 + l[i - 1];
        if (d2 > x) {
          break;
        } else {
          d1 = d2;
