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<bits/stdc++.h>
using namespace std;
#define ll long long
#define loop(i,x,n) for(ll i = x;i<n;i++)

int main()
{
  ll n,x;
  cin>>n>>x;
  vector<ll> v(n);
  loop(i,0,n)cin>>v[i];
  map<ll,ll> m;
  ll curr = 0;
  m[curr]++;
  loop(i,0,n){
    curr += v[i];
    m[curr]++;
  }
  cout<<m[x];
