<p>You are given an integer array <code>nums</code> and a <strong>positive</strong> integer <code>k</code>.</p>
|
|
|
|
<p>Return <em>the number of subarrays where the <strong>maximum</strong> element of </em><code>nums</code><em> appears <strong>at least</strong> </em><code>k</code><em> times in that subarray.</em></p>
|
|
|
|
<p>A <strong>subarray</strong> is a contiguous sequence of elements within an array.</p>
|
|
|
|
<p> </p>

|
<p><strong class="example">Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [1,3,2,3,3], k = 2
|
|
<strong>Output:</strong> 6
|
|
<strong>Explanation:</strong> The subarrays that contain the element 3 at least 2 times are: [1,3,2,3], [1,3,2,3,3], [3,2,3], [3,2,3,3], [2,3,3] and [3,3].
