Alice has a hand of cards, given as an array of integers.
Now she wants to rearrange the cards into groups so that each group is size W, and consists of W consecutive cards.
Return true if and only if she can.
Input: hand = [1,2,3,6,2,3,4,7,8], W = 3 Output: true Explanation: Alice's hand can be rearranged as [1,2,3],[2,3,4],[6,7,8].
Input: hand = [1,2,3,4,5], W = 4 Output: false Explanation: Alice's hand can't be rearranged into groups of 4.
- 1 <= hand.length <= 10000
- 0 <= hand[i]<= 10^9
- 1 <= W <= hand.length
