+ * 1482. Minimum Number of Days to Make m Bouquets
+ * https://leetcode.com/problems/minimum-number-of-days-to-make-m-bouquets/
+ * Difficulty: Medium
+ *
+ * You are given an integer array bloomDay, an integer m and an integer k.
+ *
+ * You want to make m bouquets. To make a bouquet, you need to use k adjacent flowers from the
+ * garden.
+ *
+ * The garden consists of n flowers, the ith flower will bloom in the bloomDay[i] and then can be
+ * used in exactly one bouquet.
+ *
+ * Return the minimum number of days you need to wait to be able to make m bouquets from the garden.
+ * If it is impossible to make m bouquets return -1.
