<p>给你一个整数数组 <code>arr</code>，请你将该数组分隔为长度 <strong>最多 </strong>为 k 的一些（连续）子数组。分隔完成后，每个子数组的中的所有值都会变为该子数组中的最大值。</p>
|
||
|
||
<p>返回将数组分隔变换后能够得到的元素最大和。本题所用到的测试用例会确保答案是一个 32 位整数。</p>

<p><strong>示例 1：</strong></p>
|
||
|
||
<pre>
|
||
<strong>输入：</strong>arr = [1,15,7,9,2,5,10], k = 3
|
||
<strong>输出：</strong>84
|
||
<strong>解释：</strong>数组变为 [15,15,15,9,10,10,10]</pre>

<p><strong>示例 2：</strong></p>
|
||
|
||
<pre>
|
||
<strong>输入：</strong>arr = [1,4,1,5,7,3,6,1,9,9,3], k = 4
|
||
<strong>输出：</strong>83
