846. Hand of Straights Medium

1/**
2 * [846] Hand of Straights
3 *
4 * 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.
5 * Given an integer array hand where hand[i] is the value written on the i^th card and an integer groupSize, return true if she can rearrange the cards, or false otherwise.
6 *  
7 * Example 1:
8 * 
9 * Input: hand = [1,2,3,6,2,3,4,7,8], groupSize = 3
10 * Output: true
11 * Explanation: Alice's hand can be rearranged as [1,2,3],[2,3,4],[6,7,8]
12 * 
13 * Example 2:
14 * 
15 * Input: hand = [1,2,3,4,5], groupSize = 4
16 * Output: false
17 * Explanation: Alice's hand can not be rearranged into groups of 4.
18 * 
19 *  
20 * Constraints:
21 * 
22 * 	1 <= hand.length <= 10^4
23 * 	0 <= hand[i] <= 10^9
24 * 	1 <= groupSize <= hand.length
25 * 
26 *
