For example, the subarray <code>[3, 4]</code> is an incremovable subarray of <code>[5, 3, 4, 6, 7]</code> because removing this subarray changes the array <code>[5, 3, 4, 6, 7]</code> to <code>[5, 6, 7]</code> which is strictly increasing.</p>\n\n<p>Return <em>the total number of <strong>incremovable</strong> subarrays of</em> <code>nums</code>.</p>\n\n<p><strong>Note</strong> that an empty array is considered strictly increasing.</p>\n\n<p>A <strong>subarray</strong> is a contiguous non-empty sequence of elements within an array.</p>\n\n<p>&nbsp;</p>\n<p><strong class=\"example\">Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> nums = [1,2,3,4]\n<strong>Output:</strong> 10\n<strong>Explanation:</strong> The 10 incremovable subarrays are: [1], [2], [3], [4], [1,2], [2,3], [3,4], [1,2,3], [2,3,4], and [1,2,3,4], because on removing any one of these subarrays nums becomes strictly increasing.
