Simple Calculator Command ID:2586 JAVA

  

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:
120D6

Output:
20

Example Input/Output 3:
Input:
1405d10

Output:
140
