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 Kotlin (1.0.0) (judge verdict: Accepted)

fun main(args:Array<String>) {
    val (n,x) = readLine()!!.split(" ").map { it.toInt() }
    val list = readLine()!!.split(" ").map { it.toInt() }

    var pos = 0
    for(i in (0..list.size)) {
        if(i == 0) {
            continue
        }
        val newPos = pos + list[i-1]
        if(newPos > x) {
            println(i)
            return
        }
        pos = newPos
    }
    println(n + 1)
}
