java写的，String的比较貌似用"=="不行，要用s.compare是否为0或用s.equals(s`);

import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.math.BigInteger;
import java.util.Scanner;



public class Main {


	public static void main(String[] args) throws FileNotFoundException {
		// TODO Auto-generated method stub
//		File file = new File("a.txt");
		Scanner cin = new Scanner(new BufferedInputStream(System.in));
		BigInteger a, b;
		String s;
		while(cin.hasNext()){
			a = cin.nextBigInteger();
			s = cin.next();
			b = cin.nextBigInteger();
			if(s.compareTo("/") == 0)System.out.println(a.divide(b));
//			System.out.println(s);
			else if(s.compareTo("%") == 0)System.out.println(a.mod(b));
//			if(s == "/"){
//				System.out.println(1);
//			}
//			else if(s == "%"){
//				System.out.println(a);
//			}
		}
	}
