Write a python program to create a menu-driven calculator that performs the basic arithmetic operations (+, -, *, /, and %).

Input

The input will be a single line containing two integers and operator (+, -, *, /, and %) similar to 3 5.

Output

If the given operator is “+”, print the sum of two numbers.

If the given operator is “-“, print the result of the subtraction of the two numbers.

If the given operator is “*”, print the multiplication of the two numbers.

If the given operator is “/”, print the result of the division of the two numbers.

If the given operator is “%”, print the result of the modulus operation of the two numbers.

Explanation

For example, if the given operator is “+” and the two numbers are 3 and 5. As it is an addition operator, your code should print the sum of the given two numbers (3 + 5), which is 8.

Similarly, if the given operator is “* and the two numbers are 2 and 5. As it is a multiplication operator, your code should print the result of the multiplication of the given two numbers (2 * 5), which is 10.

Similarly, if the given operator is “-” and the two numbers are 10 and 9. As it is a subtraction operator, your code should print the result of the subtraction of the given two numbers (10 – 9), which is 1.

Sample Input 1

3 + 5

Sample Output 1

8

**Code:**

```
string=input().split()
a=string[0]
b=string[2]
a=int(a)
b=int(b)
if string[1]=="+":
d=a+b
print(d)
elif string[1]=="-":
d=a-b
print(d)
elif string[1]=="*":
d=a*b
print(d)
elif string[1]=="/":
d=a/b
print(d)
elif string[1]=="%":
d=a%b
print(d)
```

Input

10 * 10

Output

100
