Maximize Kilometers

You have a vehicle that can go a certain distance based on a given amount of fuel. You have a list of fueling stations, each with a distance from your current location and an amount of fuel they provide. Your task is to maximize the distance you can travel with a limited initial amount of fuel. Implement a function that reads from standard input and outputs the maximum distance you can reach. Example: Input: 3 10 3 8 5 7 5 10 Output: 15 Input Description: The first line contains two integers n and fuel (1 ≤ n ≤ 10^5, 1 ≤ fuel ≤ 1000). The second line contains n integers indicating the distances of the fueling stations. The third line contains n integers indicating the fuel given at each station, respectively.
