<p>There is a bookstore owner that has a store open for <code>n</code> minutes. You are given an integer array <code>customers</code> of length <code>n</code> where <code>customers[i]</code> is the number of the customers that enter the store at the start of the <code>i<sup>th</sup></code> minute and all those customers leave after the end of that minute.</p>
|
|
|
|
<p>During certain minutes, the bookstore owner is grumpy. You are given a binary array grumpy where <code>grumpy[i]</code> is <code>1</code> if the bookstore owner is grumpy during the <code>i<sup>th</sup></code> minute, and is <code>0</code> otherwise.</p>
|
|
|
|
<p>When the bookstore owner is grumpy, the customers entering during that minute are not <strong>satisfied</strong>. Otherwise, they are satisfied.</p>
|
|
|
|
<p>The bookstore owner knows a secret technique to remain <strong>not grumpy</strong> for <code>minutes</code> consecutive minutes, but this technique can only be used <strong>once</strong>.</p>
|
|
|
|
<p>Return the <strong>maximum</strong> number of customers that can be <em>satisfied</em> throughout the day.</p>
|

<p><strong class="example">Example 1:</strong></p>
|
|
|
|
<div class="example-block">
|
|
<p><strong>Input:</strong> <span class="example-io">customers = [1,0,1,2,1,1,7,5], grumpy = [0,1,0,1,0,1,0,1], minutes = 3</span></p>
|
|
|
|
<p><strong>Output:</strong> <span class="example-io">16</span></p>
|
|
|
|
<p><strong>Explanation:</strong></p>
|
|
|
|
<p>The bookstore owner keeps themselves not grumpy for the last 3 minutes.</p>
|
|
|
|
<p>The maximum number of customers that can be satisfied = 1 + 1 + 1 + 1 + 7 + 5 = 16.</p>
