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: Accepted)

#include <stdio.h>

int main() {
  int A,B;
  scanf("%d %d",&A, &B);
  int sum, dif, mul, max;
  sum = A + B;
  dif = A - B;
  mul = A * B;
  // printf("%d %d %d\n",sum, dif, mul);
  max = sum;
  if (max < dif) max = dif;
  if (max < mul) max = mul;
  printf("%d\n",max);
  return 0;
}
