Problem:
Score : 100 points

Problem Statement

We have two integers: A and B.

Print the largest number among A + B, A - B, and A \times B.

Constraints

All values in input are integers.

-100 \leq A,\ B \leq 100

Input

Input is given from Standard Input in the following format:

A B

Output

Print the largest number among A + B, A - B, and A \times B.

Sample Input 1

-13 3

Sample Output 1

-10

The largest number among A + B = -10, A - B = -16, and A \times B = -39 is -10.

Sample Input 2

1 -33

Sample Output 2

34

The largest number among A + B = -32, A - B = 34, and A \times B = -33 is 34.

Sample Input 3

13 3

Sample Output 3

39

The largest number among A + B = 16, A - B = 10, and A \times B = 39 is 39.

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>
 int main (void){
   int a,b,c,d,e;
   scanf("%d",&a);
   scanf("%d",&b);
   c=a+b;
   d=a-b;
   e=a*b;
   if(c>=d && c>=e){
     printf("%d",c);
       }
   if(d>c && d>=e){
     printf("%d",b);
      }
   if(e>c && e>d){
     printf("%d",e);
     }
   return 0;
   }
