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.
Example 1:
Input: hand = [1,2,3,6,2,3,4,7,8], W = 3 Output: true Explanation: Alice'shand
can be rearranged as[1,2,3],[2,3,4],[6,7,8]
.
Example 2:
Input: hand = [1,2,3,4,5], W = 4 Output: false Explanation: Alice'shand
can't be rearranged into groups of4
.
Note:
1 <= hand.length <= 10000
0 <= hand[i] <= 10^9
1 <= W <= hand.length
