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 <= 10^4
0 <= hand[i] <= 10^9
1 <= groupSize <= hand.length
