# 绝对值表达式的最大值

<p>给你两个长度相等的整数数组，返回下面表达式的最大值：</p>

<p><code>|arr1[i] - arr1[j]| + |arr2[i] - arr2[j]| + |i - j|</code></p>

<p>其中下标 <code>i</code>，<code>j</code> 满足&nbsp;<code>0 &lt;= i, j &lt; arr1.length</code>。</p>

<p>&nbsp;</p>

<p><strong>示例 1：</strong></p>

<pre><strong>输入：</strong>arr1 = [1,2,3,4], arr2 = [-1,4,5,6]
<strong>输出：</strong>13
</pre>

<p><strong>示例 2：</strong></p>

<pre><strong>输入：</strong>arr1 = [1,-2,-5,0,10], arr2 = [0,-2,-1,-7,-4]
<strong>输出：</strong>20</pre>

<p>&nbsp;</p>

<p><strong>提示：</strong></p>

<ul>
	<li><code>2 &lt;= arr1.length == arr2.length &lt;= 40000</code></li>
	<li><code>-10^6 &lt;= arr1[i], arr2[i] &lt;= 10^6</code></li>
</ul>
