Maximum Candies Allocated to K Children

You are given a 0-indexed integer array candies, where each element denotes a pile of candies of size candies[i]. You have the flexibility to divide each pile into any number of sub-piles, but merging two piles is not allowed.

Additionally, an integer k is provided. Your task is to allocate the piles of candies to k children in a fair manner, ensuring that each child receives the same number of candies. Each child can take at most one pile of candies, and it's possible that some piles of candies may remain unused.

Your goal is to determine and print the maximum number of candies that each child can receive.
