 ## Description
+There is a bookstore owner that has a store open for `n` minutes. Every minute, some number of customers enter the store. You are given an integer array `customers` of length `n` where `customers[i]` is the number of the customer that enters the store at the start of the i<sup>th</sup> minute and all those customers leave after the end of that minute.
+
+On some minutes, the bookstore owner is grumpy. You are given a binary array grumpy where `grumpy[i]` is `1` if the bookstore owner is grumpy during the i<sup>th</sup> minute, and is `0` otherwise.
+
+When the bookstore owner is grumpy, the customers of that minute are not satisfied, otherwise, they are satisfied.
+
+The bookstore owner knows a secret technique to keep themselves not grumpy for `minutes` consecutive minutes, but can only use it once.
+
+Return the maximum number of customers that can be satisfied throughout the day.
 
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
+Input: customers = [1,0,1,2,1,1,7,5], grumpy = [0,1,0,1,0,1,0,1], minutes = 3
+Output: 16
+Explanation: The bookstore owner keeps themselves not grumpy for the last 3 minutes. 
+The maximum number of customers that can be satisfied = 1 + 1 + 1 + 1 + 7 + 5 = 16.
