846 - Hand of Straights\. Medium Alice has some number of cards and she wants to rearrange the cards into groups so that each group is of size `groupSize`, and consists of `groupSize` consecutive cards. Given an integer array `hand` where `hand[i]` is the value written on the ith card and an integer `groupSize`, return `true` if she can rearrange the cards, or `false` otherwise. **Example 1:** **Input:** hand = [1,2,3,6,2,3,4,7,8], groupSize = 3 **Output:** true **Explanation:** Alice's hand can be rearranged as [1,2,3],[2,3,4],[6,7,8] **Example 2:** **Input:** hand = [1,2,3,4,5], groupSize = 4 **Output:** false **Explanation:** Alice's hand can not be rearranged into groups of 4. **Constraints:** * 1 <= hand.length <= 104 * 0 <= hand[i] <= 109 * `1 <= groupSize <= hand.length` **Note:** This question is the same as 1296: [https://leetcode.com/problems/divide-array-in-sets-of-k-consecutive-numbers/](https://leetcode.com/problems/divide-array-in-sets-of-k-consecutive-numbers/)
