<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>
|
|
|
|
<p>Implement the <code>ParkingSystem</code> class:</p>
|
|
|
|
<ul>
|
|
<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>
|
|
<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>
|
|
</ul>
|

|
|
|
|
<pre>
|
|
<strong>Input</strong>
|
|
["ParkingSystem", "addCar", "addCar", "addCar", "addCar"]
|
|
[[1, 1, 0], [1], [2], [3], [1]]
|
|
<strong>Output</strong>
|
|
[null, true, true, false, false]
|
|
|
|
<strong>Explanation</strong>
|
|
ParkingSystem parkingSystem = new ParkingSystem(1, 1, 0);
|
|
parkingSystem.addCar(1); // return true because there is 1 available slot for a big car
|
|
parkingSystem.addCar(2); // return true because there is 1 available slot for a medium car
|
|
parkingSystem.addCar(3); // return false because there is no available slot for a small car
|
|
parkingSystem.addCar(1); // return false because there is no available slot for a big car. It is already occupied.

|
<p><strong>Constraints:</strong></p>
|
|
|
|
<ul>
|
|
<li><code>0 <= big, medium, small <= 1000</code></li>
|
|
<li><code>carType</code> is <code>1</code>, <code>2</code>, or <code>3</code></li>
|
|
<li>At most <code>1000</code> calls will be made to <code>addCar</code></li>
|
|
</ul>
