A string S is passed as input. S will contain two integer values separated by one of these alphabets - A, S, M, D where
- A or a is for addition
- S or s is for subtraction
- M or m is for multiplication
- D or d is for division

The program must perform the necessary operation and print the result as the output. (Ignore any floating point values just print the integer result.)

Input Format:The first line contains S.

Output Format:The first line contains the resulting integer value.

Boundary Conditions:Length of S is from 3 to 100.

Example Input/Output 1:
Input:
5A11
Output:
16
Explanation:
As the alphabet is A, 5 and 11 are added giving 16.

Example Input/Output 2:

Input:
1405d10

Output:140

Code:


 #include <iostream> 
using namespace std;
int main(int argc, char** argv)
{
int a,b;
char ch;
cin>>a>>ch>>b;
switch(ch)
{
case 'A':case 'a':cout<<a+b;break;
case 'S':case 's':cout<<a-b;break;
case 'M':case 'm':cout<<a*b;break;
case 'D':case 'd':cout<<a/b;break;
}
