Problem:
Simple Calculator

Write a program which reads two integers a, b and an operator op, and then prints the value of a op b.

The operator op is '+', '-', '*' or '/' (sum, difference, product or quotient). The division should truncate any fractional part.

Input

The input consists of multiple datasets. Each dataset is given in the following format.

a op b

The input ends with a dataset where op = '?'. Your program should not process for this dataset.

Output

For each dataset, print the value in a line.

Constraints

0 ≤ a, b ≤ 20000

No divisions by zero are given.

Sample Input 1

1 + 2
56 - 18
13 * 2
100 / 10
27 + 81
0 ? 0

Sample Output 1

3
38
26
10
108

Solution in JAVA (judge verdict: Wrong Answer)


import java.util.Scanner;

public class Main{
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        int i = 0;
        for(;i<100;i++){
            String str = sc.nextLine();
            String[] str2 = str.split(" ");
            int a = Integer.parseInt(str2[0]);
            String x = str2[1];
            int b = Integer.parseInt(str2[2]);
            
           
            if(x.equals("+")){
                System.out.printf("%d¥n",a+b);
            }
            if(x.equals("-")){
                System.out.printf("%d¥n",a-b);
            }
            if(x.equals("*")){
                System.out.printf("%d¥n",a*b);
            }
            if(x.equals("/")){
                System.out.printf("%d¥n",a/b);
            }
            if(x.equals("?")){
                break;
