"content": "<p>You are given a <strong>0-indexed</strong> integer array <code>candies</code>. Each element in the array denotes a pile of candies of size <code>candies[i]</code>. You can divide each pile into any number of <strong>sub piles</strong>, but you <strong>cannot</strong> merge two piles together.</p>\n\n<p>You are also given an integer <code>k</code>. You should allocate piles of candies to <code>k</code> children such that each child gets the <strong>same</strong> number of candies. Each child can take <strong>at most one</strong> pile of candies and some piles of candies may go unused.</p>\n\n<p>Return <em>the <strong>maximum number of candies</strong> each child can get.</em></p>\n<p> </p>\n<p><strong class=\"example\">Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> candies = [5,8,6], k = 3\n<strong>Output:</strong> 5\n<strong>Explanation:</strong> 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.\n</pre>\n\n<p><strong class=\"example\">Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> candies = [2,5], k = 11\n<strong>Output:</strong> 0\n<strong>Explanation:</strong> 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.\n</pre>\n\n<p> </p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>1 <= candies.length <= 10<sup>5</sup></code></li>\n\t<li><code>1 <= candies[i] <= 10<sup>7</sup></code></li>\n\t<li><code>1 <= k <= 10<sup>12</sup></code></li>\n</ul>\n",
