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 Rust (1.15.1) (judge verdict: Wrong Answer)

fn main() {
    let (n,x) = {
        let mut inputline = String::new();
        std::io::stdin().read_line(&mut inputline).ok();
        let mut inpuline  = inputline.split_whitespace();
        (inpuline.next().unwrap().parse::<i32>().unwrap(),
        inpuline.next().unwrap().parse::<i32>().unwrap(),)
    };
    let l = {
        let mut inputline = String::new();
        std::io::stdin().read_line(&mut inputline).ok();
        inputline.split_whitespace()
            .map(|x|x.parse::<i32>().unwrap())
            .collect::<Vec<i32>>()
    };
    let sum = {
        let mut temp = 0;
        let mut result = 0;
        for (i,v) in l.into_iter().enumerate(){
            temp += v;
            if temp > x {
                result = i + 1 ;
                break;
            }
        }
        result
    };
    println!("{}",sum);
}
