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 (GCC 5.4.1) (judge verdict: Accepted)

#include<stdio.h>

int main(){
  int n,x;
  int i;
  int a = 0;
  int d = 0;

  scanf("%d %d",&n,&x);

  if(1>n || n>100)return 0;
  if(1>x || x>10000)return 0;

  int L[n];

  for(i=0;i<n;i++){
    scanf("%d",&L[i]);
  }

  for(i=0;i<=n;i++){
    if(i!=0)d = d + L[i-1];
    if(i==0)d=0;

    if(d>x)break;
    else a++;
  }

  printf("%d\n",a);

  return 0;
}
