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 ()
{
	int a, b;
	scanf("%d %d", &a, &b);
	int x, y, z, bggst;

	x = a+b;
	y = a-b;
	z = a*b;
	//bggst = (x>y)?(x>z)?x:z:(y>z)?y:z;

	if(x>y && x>z)
        bggst = x;
    else if(y>x && y>z)
        bggst = y;
    else bggst = z;
    
	printf("%d\n", bggst);
	printf("The largest number among A+B=%d, A−B=%d, and A×B=%d is %d.", x, y, z, bggst);

	return 0;
