中文文档

Description

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's hand 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's hand can't be rearranged into groups of 4.

 

Note:

<li><code>1 &lt;= hand.length &lt;= 10000</code></li>

<li><code>0 &lt;= hand[i]&nbsp;&lt;= 10^9</code></li>

<li><code>1 &lt;= W &lt;= hand.length</code></li>
