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 Julia (0.5.0) (judge verdict: Accepted)

parseInt(x) = parse(Int,x)

function main()
  (N,X) = map(parseInt,split(readline()))
  L = map(parseInt,split(readline()))
  D = zeros(Int64,N+1)
  for i=1:N
    D[i+1] = D[i]+L[i]
  end
  j = 0 
  for i = 1:(N+1)
    if X >= D[i]
      j = i 
    end
  end
  println(j)
end
  
main()
