Truck Parcel Loading

In this problem, you are given a series of parcels with individual weights and a truck that has a maximum weight capacity $W$. The parcels are loaded one by one in the given order until adding the next parcel would cause the total weight to exceed $W$. Your task is to determine how many parcels can be loaded without exceeding the weight limit.

For example, if there are 6 parcels with weights [50, 40, 60, 30, 70, 20] and the truck's capacity is 150, then the truck can load the first 3 parcels (50 + 40 + 60 = 150) exactly. The answer in this case would be 3.

Note: The parcels must be loaded in the order they are given.

inputFormat

The input is read from standard input (stdin) and consists of two lines:

1. The first line contains two integers $m$ and $W$, where $m$ is the number of parcels and $W$ is the truck's weight limit.
2. The second line contains $m$ space-separated integers representing the weights of the parcels in the order they must be loaded.

outputFormat

Output a single integer to standard output (stdout): the number of parcels that can be loaded before the total weight exceeds the weight limit $W$.## sample
