采集果实

/*
题目思路：
1. 使用 Java Stream API 处理数组。
2. 计算每一批次的采集时间，并累加所有批次的采集时间。

import java.util.Arrays;

public class FruitCollectionStream {
    public int minTimeToCollectFruits(int[] time, int[][] fruits, int limit) {
        return Arrays.stream(fruits)
                .mapToInt(fruit -> {
                    int type = fruit[0];
                    int num = fruit[1];
                    int rounds = (num + limit - 1) / limit;  // 向上取整计算需要采集的次数
                    return rounds * time[type];
                })
                .sum();
    }

    public static void main(String[] args) {
        FruitCollectionStream fc = new FruitCollectionStream();
        int[] time = {2, 3, 2};
        int[][] fruits = {{0, 2}, {1, 4}, {2, 1}};
        int limit = 3;
        System.out.println(fc.minTimeToCollectFruits(time, fruits, limit));  // 输出 10
    }
}
