Today, the bookstore owner has a store open for customers.length minutes.
Every minute, some number of customers (customers[i]) enter the store, and all
those customers leave after the end of that minute.
On some minutes, the bookstore owner is grumpy. If the bookstore owner is grumpy on the
i-th minute, grumpy[i] = 1, otherwise grumpy[i] = 0. 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
X minutes straight, but can only use it once.
Return the maximum number of customers that can be satisfied throughout the day.
Example 1:
Input: customers = [1,0,1,2,1,1,7,5], grumpy = [0,1,0,1,0,1,0,1], X = 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.
Note:
1 <= X <= customers.length == grumpy.length <= 20000
0 <= customers[i] <= 10000 <= grumpy[i] <= 1
