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, i, result  = 0;
    int L[100];
    int D[100];

    scanf("%d",&N);
    scanf("%d",&X);

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

    for(i = 0; i < N+1; i++){
        if(i == 0){
            D[i] = 0;
        }else{
            D[i] = D[i-1] + L[i-1];
        }
        if(D[i] <= X){
            result++;
        }
    }

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

    return 0;
}
