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-----
3 6
3 4 5

-----Sample Output-----
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.
