|
|
|
<p> </p>
|
|
<p><strong>Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [4,3,2,3,5,2,1], k = 4
|
|
<strong>Output:</strong> true
|
|
<strong>Explanation:</strong> It is possible to divide it into 4 subsets (5), (1, 4), (2,3), (2,3) with equal sums.

|
</pre>
|
|
|
|
<p><strong>Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [1,2,3,4], k = 3
|
|
<strong>Output:</strong> false
|
|
</pre>

|
|
|
<p> </p>
|
|
<p><strong>Constraints:</strong></p>
|
|
|
|
<ul>
|
|
<li><code>1 <= k <= nums.length <= 16</code></li>
|
|
<li><code>1 <= nums[i] <= 10<sup>4</sup></code></li>
|
|
<li>The frequency of each element is in the range <code>[1, 4]</code>.</li>
|
|
</ul>
