"content": "<p>Design a parking system for a parking lot. The parking lot has three kinds of parking spaces: big, medium, and small, with a fixed number of slots for each size.</p>\n\n<p>Implement the <code>ParkingSystem</code> class:</p>\n\n<ul>\n\t<li><code>ParkingSystem(int big, int medium, int small)</code> Initializes object of the <code>ParkingSystem</code> class. The number of slots for each parking space are given as part of the constructor.</li>\n\t<li><code>bool addCar(int carType)</code> Checks whether there is a parking space of <code>carType</code> for the car that wants to get into the parking lot. <code>carType</code> can be of three kinds: big, medium, or small, which are represented by <code>1</code>, <code>2</code>, and <code>3</code> respectively. <strong>A car can only park in a parking space of its </strong><code>carType</code>. If there is no space available, return <code>false</code>, else park the car in that size space and return <code>true</code>.</li>\n</ul>\n\n<p> </p>\n<p><strong class=\"example\">Example 1:</strong></p>\n\n<pre>\n<strong>Input</strong>\n["ParkingSystem", "addCar", "addCar", "addCar", "addCar"]\n[[1, 1, 0], [1], [2], [3], [1]]\n<strong>Output</strong>\n[null, true, true, false, false]\n\n<strong>Explanation</strong>\nParkingSystem parkingSystem = new ParkingSystem(1, 1, 0);\nparkingSystem.addCar(1); // return true because there is 1 available slot for a big car\nparkingSystem.addCar(2); // return true because there is 1 available slot for a medium car\nparkingSystem.addCar(3); // return false because there is no available slot for a small car\nparkingSystem.addCar(1); // return false because there is no available slot for a big car.
