数据结构与算法

Personal experience with Leetcode
Note: if possible, don't practice with Python, Java and CPP would be better choice.

• Java输入格式：

import java.util.Scanner;

public class Test {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		while(sc.hasNext()) {
			String[] str1 = sc.nextLine().trim().split(" ");
			String[] str2 = sc.nextLine().trim().split(" ");
			String[] str3 = sc.nextLine().trim().split(" ");

			System.out.println(Arrays.toString(str1));
			System.out.println(Arrays.toString(str2));
			System.out.println(Arrays.toString(str3));
		}
	}
}
