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>

#include<stdlib.h>

int meuMax(int a, int b){
	if (a> b)
		return a;
	return b;
}

int main(){
	int a, b, eq1=0, eq2=0, eq3=0, maior=0, maior2=0;
	scanf("%d %d", &a, &b);
	eq1= a+b;
	eq2= a-b;
	eq3= a*b;

	maior= meuMax(eq1,eq2);
	maior2= meuMax(maior, eq3);
	printf("%d\n", maior2);

    return 0;
}
