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)

// 文字列変換等
fun main(args: Array<String>) {
    var inputs = readInputLine().split(" ").map { Integer.parseInt(it) }
    val n = inputs[0]
    val x = inputs[1]

    inputs = readInputLine().split(" ").map { Integer.parseInt(it) }
    
    var pos = 0
    var ans = 1
    
    for (i in 0 until n) {
        pos += inputs[i]
        if (pos <= x) {
            ans++
        } else {
            break
        }
    }
    
    println("$ans")
}
 
fun readInputLine(): String {
    return readLine()!!
}
