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(void) {
   
   int N,X;
   
   scanf("%d%d",&N,&X);
   
   int i;
   int L[N];
   
   for (i = 0; i < N; i++) {
      scanf("%d",&L[i]);
   }
   
   int D[N+1];
   
   D[0] = 0;
   
   int ans = 0;
   for (i = 1;i < N+1;i++) {
      D[i] = D[i - 1] + L[i - 1];
      if (D[i] <= X) {
         ans++;
      }
   }
   
   if (D[0] <= X) {
      ans++;
   }
   
   printf("%d\n",ans);
   
   return 0;
   
}
