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 9.2.1) (judge verdict: Wrong Answer)

#include <stdio.h>
#include <string.h>

int main(void){

  //char s[11];
  int a,b = 0;
  scanf("%d %d", &a, &b);
  //scanf("%d", &b);

  if((a+b)>a*b && (a+b)>(a-b)) printf("%d", a+b);
  else if((a-b)>a*b && (a-b)>(a+b)) printf("%d", a-b);
  else if((a+b)<a*b && (a-b)<(a*b)) printf("%d", a*b);

   

  return 0;
}
