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 JavaScript (node.js v5.12) (judge verdict: Wrong Answer)

function main(input) {
  const args = input.split('\n');
  const items1 = args[0].split(' ').map(i => parseInt(i));
  const N = items1[0];
  const X = items1[1];
  const List = args[1].split(' ').map(i => parseInt(i));

  for (var i = 1; i <= N; i++) {
    var total = List.slice(0, i).reduce((x, y) => x + y, 0);
    if (total > X) {
      console.log(i);
      return;
    }
  }
  console.log(N);
}
main(require('fs').readFileSync('/dev/stdin', 'utf8'));
