"content": "<p>You have <code>n</code> boxes labeled from <code>0</code> to <code>n - 1</code>. You are given four arrays: <code>status</code>, <code>candies</code>, <code>keys</code>, and <code>containedBoxes</code> where:</p>\n\n<ul>\n\t<li><code>status[i]</code> is <code>1</code> if the <code>i<sup>th</sup></code> box is open and <code>0</code> if the <code>i<sup>th</sup></code> box is closed,</li>\n\t<li><code>candies[i]</code> is the number of candies in the <code>i<sup>th</sup></code> box,</li>\n\t<li><code>keys[i]</code> is a list of the labels of the boxes you can open after opening the <code>i<sup>th</sup></code> box.</li>\n\t<li><code>containedBoxes[i]</code> is a list of the boxes you found inside the <code>i<sup>th</sup></code> box.</li>\n</ul>\n\n<p>You are given an integer array <code>initialBoxes</code> that contains the labels of the boxes you initially have. You can take all the candies in <strong>any open box</strong> and you can use the keys in it to open new boxes and you also can use the boxes you find in it.</p>\n\n<p>Return <em>the maximum number of candies you can get following the rules above</em>.</p>\n\n<p> </p>\n<p><strong>Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> status = [1,0,1,0], candies = [7,5,4,100], keys = [[],[],[1],[]], containedBoxes = [[1,2],[3],[],[]], initialBoxes = [0]\n<strong>Output:</strong> 16\n<strong>Explanation:</strong> You will be initially given box 0. You will find 7 candies in it and boxes 1 and 2.\nBox 1 is closed and you do not have a key for it so you will open box 2. You will find 4 candies and a key to box 1 in box 2.\nIn box 1, you will find 5 candies and box 3 but you will not find a key to box 3 so box 3 will remain closed.\nTotal number of candies collected = 7 + 4 + 5 = 16 candy.\n</pre>\n\n<p><strong>Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> status = [1,0,0,0,0,0], candies = [1,1,1,1,1,1], keys = [[1,2,3,4,5],[],[],[],[],[]], containedBoxes = [[1,2,3,4,5],[],[],[],[],[]], initialBoxes = [0]\n<strong>Output:</strong> 6\n<strong>Explanation:</strong> You have initially box 0.
