<p>8 间牢房排成一排,每间牢房不是有人住就是空着。</p>
|
||
|
||
<p>每天,无论牢房是被占用或空置,都会根据以下规则进行更改:</p>
|
||
|
||
<ul>
|
||
<li>如果一间牢房的两个相邻的房间都被占用或都是空的,那么该牢房就会被占用。</li>
|
||
<li>否则,它就会被空置。</li>
|
||
</ul>
|
||
|
||
<p>(请注意,由于监狱中的牢房排成一行,所以行中的第一个和最后一个房间无法有两个相邻的房间。)</p>
|
||
|
||
<p>我们用以下方式描述监狱的当前状态:如果第 <code>i</code> 间牢房被占用,则 <code>cell[i]==1</code>,否则 <code>cell[i]==0</code>。</p>
|
||
|
||
<p>根据监狱的初始状态,在 <code>N</code> 天后返回监狱的状况(和上述 N 种变化)。</p>

<p><strong>示例 1:</strong></p>
|
||
|
||
<pre><strong>输入:</strong>cells = [0,1,0,1,1,0,0,1], N = 7
|
||
<strong>输出:</strong>[0,0,1,1,0,0,0,0]
|
||
<strong>解释:
|
||
</strong>下表概述了监狱每天的状况:
|
||
Day 0: [0, 1, 0, 1, 1, 0, 0, 1]
|
||
Day 1: [0, 1, 1, 0, 0, 0, 0, 0]
|
||
Day 2: [0, 0, 0, 0, 1, 1, 1, 0]
|
||
Day 3: [0, 1, 1, 0, 0, 1, 0, 0]
|
||
Day 4: [0, 0, 0, 0, 0, 1, 0, 0]
|
||
Day 5: [0, 1, 1, 1, 0, 1, 0, 0]
|
||
Day 6: [0, 0, 1, 0, 1, 1, 0, 0]
|
||
Day 7: [0, 0, 1, 1, 0, 0, 0, 0]

<p><strong>示例 2:</strong></p>
|
||
|
||

<ol>
|
||
<li><code>cells.length == 8</code></li>
|
||
<li><code>cells[i]</code> 的值为 <code>0</code> 或 <code>1</code> </li>
|
