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 a,b,count,check=0;
  scanf("%d",&a);
  int c[a];
  int d[a];
  d[0] = 0;
  scanf("%d",&b);
  for(int i=0; i<a; i++){
    scanf("%d",&c[i]);
  }
  
  for(int i=0; i<=a; i++){
    if(i==0){
      check=0;
    } else{
      check = d[i-1]+c[i-1];
      d[i] = check;
     }
    
    if(check<=b){
      count++;
    }
  }
  printf("%d",count);
  return 0;
}
