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 Python3 (judge verdict: Accepted)

l=[]
while True:
    ll=[]
    a,op,b=input().split()
    ll.append(int(a))
    ll.append(op)
    ll.append(int(b))
    if op=="?":
        break
    l.append(ll)

for i in range(len(l)):
    if l[i][1]=="+":
        print(int(l[i][0]+l[i][2]))
    elif l[i][1]=="-":
        print(int(l[i][0]-l[i][2]))
    elif l[i][1]=="*":
        print(int(l[i][0]*l[i][2]))
    else:
        print(int(l[i][0]/l[i][2]))
