<p>You are given an integer array <code>nums</code>. The <strong>absolute sum</strong> of a subarray <code>[nums<sub>l</sub>, nums<sub>l+1</sub>, ..., nums<sub>r-1</sub>, nums<sub>r</sub>]</code> is <code>abs(nums<sub>l</sub> + nums<sub>l+1</sub> + ... + nums<sub>r-1</sub> + nums<sub>r</sub>)</code>.</p>
|
|
|
|
<p>Return <em>the <strong>maximum</strong> absolute sum of any <strong>(possibly empty)</strong> subarray of </em><code>nums</code>.</p>
|
|
|
|
<p>Note that <code>abs(x)</code> is defined as follows:</p>
|
|
|
|
<ul>
|
|
<li>If <code>x</code> is a negative integer, then <code>abs(x) = -x</code>.</li>
|
|
<li>If <code>x</code> is a non-negative integer, then <code>abs(x) = x</code>.</li>
|
|
</ul>
|
|
|
|

|
<p><strong class="example">Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [1,-3,2,3,-4]
|
|
<strong>Output:</strong> 5
|
|
<strong>Explanation:</strong> The subarray [2,3] has absolute sum = abs(2+3) = abs(5) = 5.
|
|
</pre>
|

<p><strong class="example">Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [2,-5,1,-4,3,-2]
|
|
<strong>Output:</strong> 8
|
|
<strong>Explanation:</strong> The subarray [-5,1,-4] has absolute sum = abs(-5+1-4) = abs(-8) = 8.
