<p>You are given an integer array <code>nums</code> and two integers <code>minK</code> and <code>maxK</code>.</p>
|
|
|
|
|
|
|
|
<p>A <strong>fixed-bound subarray</strong> of <code>nums</code> is a subarray that satisfies the following conditions:</p>
|
|
|
|
|
|
|
|
<ul>
|
|
|
|
<li>The <strong>minimum</strong> value in the subarray is equal to <code>minK</code>.</li>
|
|
|
|
<li>The <strong>maximum</strong> value in the subarray is equal to <code>maxK</code>.</li>
|
|
|
|
</ul>
|
|
|
|
|
|
|
|
<p>Return <em>the <strong>number</strong> of fixed-bound subarrays</em>.</p>
|
|
|
|
|
|
|
|
<p>A <strong>subarray</strong> is a <strong>contiguous</strong> part of an array.</p>
