"content": "<p>Given the array <code>restaurants</code> where <code>restaurants[i] = [id<sub>i</sub>, rating<sub>i</sub>, veganFriendly<sub>i</sub>, price<sub>i</sub>, distance<sub>i</sub>]</code>. You have to filter the restaurants using three filters.</p>\n\n<p>The <code>veganFriendly</code> filter will be either <em>true</em> (meaning you should only include restaurants with <code>veganFriendly<sub>i</sub></code> set to true) or <em>false</em> (meaning you can include any restaurant). In addition, you have the filters <code>maxPrice</code> and <code>maxDistance</code> which are the maximum value for price and distance of restaurants you should consider respectively.</p>\n\n<p>Return the array of restaurant <em><strong>IDs</strong></em> after filtering, ordered by <strong>rating</strong> from highest to lowest. For restaurants with the same rating, order them by <em><strong>id</strong></em> from highest to lowest. For simplicity <code>veganFriendly<sub>i</sub></code> and <code>veganFriendly</code> take value <em>1</em> when it is <em>true</em>, and <em>0</em> when it is <em>false</em>.</p>\n\n<p> </p>\n<p><strong>Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> restaurants = [[1,4,1,40,10],[2,8,0,50,5],[3,8,1,30,4],[4,10,0,10,3],[5,1,1,15,1]], veganFriendly = 1, maxPrice = 50, maxDistance = 10\n<strong>Output:</strong> [3,1,5] \n<strong>Explanation: \n</strong>The restaurants are:\nRestaurant 1 [id=1, rating=4, veganFriendly=1, price=40, distance=10]\nRestaurant 2 [id=2, rating=8, veganFriendly=0, price=50, distance=5]\nRestaurant 3 [id=3, rating=8, veganFriendly=1, price=30, distance=4]\nRestaurant 4 [id=4, rating=10, veganFriendly=0, price=10, distance=3]\nRestaurant 5 [id=5, rating=1, veganFriendly=1, price=15, distance=1] \nAfter filter restaurants with veganFriendly = 1, maxPrice = 50 and maxDistance = 10 we have restaurant 3, restaurant 1 and restaurant 5 (ordered by rating from highest to lowest). \n</pre>\n\n<p><strong>Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> restaurants = [[1,4,1,40,10],[2,8,0,50,5],[3,8,1,30,4],[4,10,0,10,3],[5,1,1,15,1]], veganFriendly = 0, maxPrice = 50, maxDistance = 10\n<strong>Output:</strong> [4,3,2,1,5]\n<strong>Explanation:</strong> The restaurants are the same as in example 1, but in this case the filter veganFriendly = 0, therefore all restaurants are considered.\n</pre>\n\n<p><strong>Example 3:</strong></p>\n\n<pre>\n<strong>Input:</strong> restaurants = [[1,4,1,40,10],[2,8,0,50,5],[3,8,1,30,4],[4,10,0,10,3],[5,1,1,15,1]], veganFriendly = 0, maxPrice = 30, maxDistance = 3\n<strong>Output:</strong> [4,5]\n</pre>\n\n<p> </p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>1 <= restaurants.length <= 10^4</code></li>\n\t<li><code>restaurants[i].length == 5</code></li>\n\t<li><code>1 <= id<sub>i</sub>, rating<sub>i</sub>, price<sub>i</sub>, distance<sub>i </sub><= 10^5</code></li>\n\t<li><code>1 <= maxPrice, maxDistance <= 10^5</code></li>\n\t<li><code>veganFriendly<sub>i</sub></code> and <code>veganFriendly</code> are 0 or 1.</li>\n\t<li>All <code>id<sub>i</sub></code> are distinct.</li>\n</ul>\n",
