+<p>Given an unsorted array of integers <code>nums</code>, return <em>the length of the longest <strong>continuous increasing subsequence</strong> (i.e. subarray)</em>. The subsequence must be <strong>strictly</strong> increasing.</p>
+
+<p>A <strong>continuous increasing subsequence</strong> is defined by two indices <code>l</code> and <code>r</code> (<code>l &lt; r</code>) such that it is <code>[nums[l], nums[l + 1], ..., nums[r - 1], nums[r]]</code> and for each <code>l &lt;= i &lt; r</code>, <code>nums[i] &lt; nums[i + 1]</code>.</p>

+<p>&nbsp;</p>
+<p><strong>Example 1:</strong></p>
+
+<pre>
+<strong>Input:</strong> nums = [1,3,5,4,7]
+<strong>Output:</strong> 3
+<strong>Explanation:</strong> The longest continuous increasing subsequence is [1,3,5] with length 3.
+Even though [1,3,5,7] is an increasing subsequence, it is not continuous as elements 5 and 7 are separated by element
+4.
+</pre>
+
+<p><strong>Example 2:</strong></p>
+
+<pre>
+<strong>Input:</strong> nums = [2,2,2,2,2]
+<strong>Output:</strong> 1
+<strong>Explanation:</strong> The longest continuous increasing subsequence is [2] with length 1. Note that it must be strictly
+increasing.
