	# Problem Statement
	> You are given a 0-indexed integer array candies. Each element in the array denotes a pile of candies of size candies[i]. You can divide each pile into any number of sub piles, but you cannot merge two piles together. You are also given an integer k. You should allocate piles of candies to k children such that each child gets the same number of candies. Each child can be allocated candies from only one pile of candies and some piles of candies may go unused. Return the maximum number of candies each child can get.   Example 1:  Input: candies = [5,8,6], k = 3 Output: 5 Explanation: We can divide candies[1] into 2 piles of size 5 and 3, and candies[2] into 2 piles of size 5 and 1. We now have five piles of candies of sizes 5, 5, 3, 5, and 1. We can allocate the 3 piles of size 5 to 3 children. It can be proven that each child cannot receive more than 5 candies.  Example 2:  Input: candies = [2,5], k = 11 Output: 0 Explanation: There are 11 children but only 7 candies in total, so it is impossible to ensure each child receives at least one candy. Thus, each child gets no candy and the answer is 0.    Constraints:  1 <= candies.length <= 105 1 <= candies[i] <= 107 1 <= k <= 1012  

	# Explanation
	Here's an efficient solution to the problem:

*   **Binary Search:** Use binary search to find the maximum number of candies each child can get. The search space is from 0 to the maximum value in the `candies` array.
*   **Check Feasibility:** For a given mid-value (potential answer), check if it's possible to allocate at least `k` piles of candies such that each pile has at least `mid` candies. Iterate through the `candies` array and for each pile, calculate how many piles of size `mid` can be formed.
*   **Adjust Search Space:** Based on the feasibility check, adjust the binary search space (left or right) to converge towards the optimal answer.

*   **Runtime Complexity:** O(n log(max(candies))), where n is the length of the candies array.
*   **Storage Complexity:** O(1)

	```python

            return 0  # Handle the case where each child gets 0 candies

        count = 0
        for pile in candies:
            count += pile // mid

        if count >= k:
            ans = mid
            left = mid + 1  # Try to find a larger value
        else:
            right = mid - 1  # Reduce the value

    return ans
