<p>You are given an integer array <code>nums</code> and an integer <code>k</code>. You can partition the array into <strong>at most</strong> <code>k</code> non-empty adjacent subarrays. The <strong>score</strong> of a partition is the sum of the averages of each subarray.</p>
|
|
|
|
<p>Note that the partition must use every integer in <code>nums</code>, and that the score is not necessarily an integer.</p>
|
|
|
|
<p>Return <em>the maximum <strong>score</strong> you can achieve of all the possible partitions</em>. Answers within <code>10<sup>-6</sup></code> of the actual answer will be accepted.</p>
|
|
|
|
<p> </p>
|
|
<p><strong>Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [9,1,2,3,9], k = 3
|
|
<strong>Output:</strong> 20.00000
|
|
<strong>Explanation:</strong>
|
|
The best choice is to partition nums into [9], [1, 2, 3], [9]. The answer is 9 + (1 + 2 + 3) / 3 + 9 = 20.
|
|
We could have also partitioned nums into [9, 1], [2], [3, 9], for example.
|
|
That partition would lead to a score of 5 + 2 + 6 = 13, which is worse.

<p><strong>Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [1,2,3,4,5,6,7], k = 4
|
|
<strong>Output:</strong> 20.50000

|
<p><strong>Constraints:</strong></p>
|
|
|
|
<ul>
|
|
<li><code>1 <= nums.length <= 100</code></li>
|
|
<li><code>1 <= nums[i] <= 10<sup>4</sup></code></li>
|
|
<li><code>1 <= k <= nums.length</code></li>

</ul>
