[zerojudge] a012 Hashmat的戰役

題目：https://zerojudge.tw/ShowProblem?problemid=a012
說明：大數運算的題目，對 Java 及 Python 來說是相對容易的。

Java 版

import java.util.Scanner;
import java.math.BigInteger;

public class A012 {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        while (in.hasNext()) {
            BigInteger a = new BigInteger(in.next());
            BigInteger b = new BigInteger(in.next());
            System.out.println(a.subtract(b).abs());
        }
    }
}

Python 版 (2022.07)

a, b = map(int, input().split(' '))
print(abs(a - b))
