<p>Given a non-empty array of non-negative integers <code>nums</code>, the <b>degree</b> of this array is defined as the maximum frequency of any one of its elements.</p>
|
|
|
|
<p>Your task is to find the smallest possible length of a (contiguous) subarray of <code>nums</code>, that has the same degree as <code>nums</code>.</p>
|
|
|
|
<p> </p>
|
|
<p><strong class="example">Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [1,2,2,3,1]
|
|
<strong>Output:</strong> 2
|
|
<strong>Explanation:</strong>
|
|
The input array has a degree of 2 because both elements 1 and 2 appear twice.
|
|
Of the subarrays that have the same degree:
|
|
[1, 2, 2, 3, 1], [1, 2, 2, 3], [2, 2, 3, 1], [1, 2, 2], [2, 2, 3], [2, 2]
|
|
The shortest length is 2. So return 2.
|
|
</pre>
|
|
|
|
<p><strong class="example">Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [1,2,2,3,1,4,2]
|
|
<strong>Output:</strong> 6
|
|
<strong>Explanation:</strong>
|
|
The degree is 3 because the element 2 is repeated 3 times.
|
|
So [2,2,3,1,4,2] is the shortest subarray, therefore returning 6.

<p> </p>
|
|
<p><strong>Constraints:</strong></p>
|
|
|
|
<ul>
|
|
<li><code>nums.length</code> will be between 1 and 50,000.</li>
|
|
<li><code>nums[i]</code> will be an integer between 0 and 49,999.</li>
|
|
</ul>
