Minimized Maximum of Products Distributed to Any Store
To solve the problem, we can use a binary search approach to find the minimum possible maximum number of products that can be given to any store. We’ll define a function to check whether a certain number of products can be distributed among the stores, and then use binary search to minimize that value.
Here’s the Python code:


This code first sorts the product types by their quantities and then uses binary search to find the minimum possible maximum number of products that can be given to any store, satisfying the constraints.

Problem Classification
Problem Statement:You are given an integer n indicating there are n specialty retail stores. There are m product types of varying amounts, which are given as a 0indexed integer array quantities, where quantities[i] represents the number of products of the ith product type.
You need to distribute all products to the retail stores following these rules:
A store can only be given at most one product type but can be given any amount of it. After distribution, each store will have been given some number of products (possibly 0). Let x represent the maximum number of products given to any store. You want x to be as small as possible, i.e., you want to minimize the maximum number of products that are given to any store. Return the minimum possible x.
Example 1:
Input: n = 6, quantities = [11,6] Output: 3 Explanation: One optimal way is:
 The 11 products of type 0 are distributed to the first four stores in these amounts: 2, 3, 3, 3
 The 6 products of type 1 are distributed to the other two stores in these amounts: 3, 3 The maximum number of products given to any store is max(2, 3, 3, 3, 3, 3) = 3. Example 2:
Input: n = 7, quantities = [15,10,10] Output: 5 Explanation: One optimal way is:
 The 15 products of type 0 are distributed to the first three stores in these amounts: 5, 5, 5
 The 10 products of type 1 are distributed to the next two stores in these amounts: 5, 5
 The 10 products of type 2 are distributed to the last two stores in these amounts: 5, 5 The maximum number of products given to any store is max(5, 5, 5, 5, 5, 5, 5) = 5. Example 3:
Input: n = 1, quantities = [100000] Output: 100000 Explanation: The only optimal way is:
 The 100000 products of type 0 are distributed to the only store. The maximum number of products given to any store is max(100000) = 100000.
Constraints:
m == quantities.length 1 <= m <= n <= 105 1 <= quantities[i] <= 105
