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:
