<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 < r</code>) such that it is <code>[nums[l], nums[l + 1], ..., nums[r - 1], nums[r]]</code> and for each <code>l <= i < r</code>, <code>nums[i] < nums[i + 1]</code>.</p> <p> </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. </pre> <p> </p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= nums.length <= 10<sup>4</sup></code></li> <li><code>-10<sup>9</sup> <= nums[i] <= 10<sup>9</sup></code></li> </ul>
