<p>Given an array of positive integers <code>nums</code>, return the <em>maximum possible sum of an <strong>ascending</strong> subarray in </em><code>nums</code>.</p>

<p>A subarray is defined as a contiguous sequence of numbers in an array.</p>

<p>A subarray <code>[nums<sub>l</sub>, nums<sub>l+1</sub>, ..., nums<sub>r-1</sub>, nums<sub>r</sub>]</code> is <strong>ascending</strong> if for all <code>i</code> where <code>l &lt;= i &lt; r</code>, <code>nums<sub>i </sub> &lt; nums<sub>i+1</sub></code>. Note that a subarray of size <code>1</code> is <strong>ascending</strong>.</p>

<p><strong class="example">Example 1:</strong></p>

<pre>
<strong>Input:</strong> nums = [10,20,30,5,10,50]
<strong>Output:</strong> 65
<strong>Explanation: </strong>[5,10,50] is the ascending subarray with the maximum sum of 65.
</pre>

<p><strong class="example">Example 2:</strong></p>

<pre>
<strong>Input:</strong> nums = [10,20,30,40,50]
<strong>Output:</strong> 150
<strong>Explanation: </strong>[10,20,30,40,50] is the ascending subarray with the maximum sum of 150.
</pre>

<p><strong class="example">Example 3:</strong></p>

<pre>
<strong>Input:</strong> nums = [12,17,15,13,10,11,12]
<strong>Output:</strong> 33
<strong>Explanation: </strong>[10,11,12] is the ascending subarray with the maximum sum of 33.

<p><strong>Constraints:</strong></p>

<ul>
	<li><code>1 &lt;= nums.length &lt;= 100</code></li>
	<li><code>1 &lt;= nums[i] &lt;= 100</code></li>
