내가 작성한 코드

import java.io.*;
import java.math.BigInteger;

public class 백준15964 {
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(System.out));

        String[] input = br.readLine().split(" ");
        BigInteger A = new BigInteger(input[0]);
        BigInteger B = new BigInteger(input[1]);

        BigInteger result = (A.add(B)).multiply(A.subtract(B));

        bw.write(result.toString());
        bw.close();
    }
}
