This is all the problems I had solved in LeetCode.

I will update this repo whenever I had solved a problem. All the solutions in this repo are written in Java.

You can follow my repo, read my code, and provide me better solution. Also, pointing out the mistakes in my solutions is welcomed.

Usage

This repository are developed under IntelliJ IDEA 2016. Therefore, you can use an IDE such as IntelliJ IDEA to open and develop directly. Or you can compile and test it with JDK.

Some of the solution had been converted to static method for the convenience of test.

//Below is a sample usage for problem: "492. Construct the Rectangle".

//ConstructTheRectangle.java
package easy;
public class ConstructTheRectangle {
    //The method has been made static, which is different from the original non-static method.
    public static int[] constructRectangle(int area) {
        int[] result = new int[2];
        int sqrt = (int) Math.sqrt(area);
        while (area % sqrt != 0) {
            sqrt--;
        }
        result[1] = sqrt;
        result[0] = area / sqrt;
        return result;
    }
}

//Main.java
import easy.ConstructTheRectangle;
public class Main {
    public static void main(String[] args) {
        //As it is a static method, we can use it directly.
        //For those non-static method, we should instantiate it before use.
        for (int edge : ConstructTheRectangle.constructRectangle(5)) {
            System.out.println(edge);
        }
    }
}

Tutorial

If you had any question after reading both the question and solutions, you can turn to the tutorials in the dictionary "tutorials" or send me a e-mail at lin-jinting@outlook.com. The solution for each problem is written in Markdown file with corresponding name. For example, the tutorial of FizzBuzz is written in FizBuzz.md.
