<p>Given an integer array <code>arr</code> and an integer <code>k</code>, modify the array by repeating it <code>k</code> times.</p>
|
|
|
|
<p>For example, if <code>arr = [1, 2]</code> and <code>k = 3 </code>then the modified array will be <code>[1, 2, 1, 2, 1, 2]</code>.</p>
|
|
|
|
<p>Return the maximum sub-array sum in the modified array. Note that the length of the sub-array can be <code>0</code> and its sum in that case is <code>0</code>.</p>
|
|
|
|
<p>As the answer can be very large, return the answer <strong>modulo</strong> <code>10<sup>9</sup> + 7</code>.</p>
|
|
|
|
<p> </p>
|
|
<p><strong>Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> arr = [1,2], k = 3
|
|
<strong>Output:</strong> 9
|
|
</pre>
|
|
|
|
<p><strong>Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> arr = [1,-2,1], k = 5
|
|
<strong>Output:</strong> 2
|
|
</pre>
|
|
|
|
<p><strong>Example 3:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> arr = [-1,-2], k = 7
|
|
<strong>Output:</strong> 0
|
|
</pre>
|
|
|
|
<p> </p>
|
|
<p><strong>Constraints:</strong></p>
|
|
|
|
<ul>
|
|
<li><code>1 <= arr.length <= 10<sup>5</sup></code></li>
|
|
<li><code>1 <= k <= 10<sup>5</sup></code></li>
|
|
<li><code>-10<sup>4</sup> <= arr[i] <= 10<sup>4</sup></code></li>
|
|
</ul>
