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 Kotlin (judge verdict: Accepted)

fun main(args: Array<String>) {
    while(true)
    {
        var list = readLine()!!.split(" ")//.map(String::toDouble)
        var a = list[0].toInt()
        var b = list[2].toInt()

        if (list[1] == "+")
        {
            println("%d".format((a+b).toInt()))
        }
        else if (list[1] == "-")
        {
            println("%d".format((a-b).toInt()))
        }
        else if (list[1] == "*")
        {
            println("%d".format((a*b).toInt()))
        }
        else if (list[1] == "/")
        {
            println("%d".format((a/b).toInt()))
        }
        else
        {
            return
        }
    }
}
