+/**
+ * 1705. Maximum Number of Eaten Apples
+ * https://leetcode.com/problems/maximum-number-of-eaten-apples/
+ * Difficulty: Medium
+ *
+ * There is a special kind of apple tree that grows apples every day for n days. On the ith day,
+ * the tree grows apples[i] apples that will rot after days[i] days, that is on day i + days[i]
+ * the apples will be rotten and cannot be eaten. On some days, the apple tree does not grow any
+ * apples, which are denoted by apples[i] == 0 and days[i] == 0.
+ *
+ * You decided to eat at most one apple a day (to keep the doctors away). Note that you can keep
+ * eating after the first n days.
+ *
+ * Given two integer arrays days and apples of length n, return the maximum number of apples you
+ * can eat.
