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: Accepted)

# include <stdio.h>
int main (void)
{   int A = 0;int B = 0;
    int a;int b;int c;int cnt;int temp;
    scanf("%d",&A);
    scanf("%d",&B);
    a = A + B;b = A - B;c = A * B;
    for (cnt = 0;cnt <= 2;cnt++)
    {   if (cnt == 0){
            temp = a;}
        else if(cnt == 1){
            if (b > temp){
                temp = b;}}
        else{
            if (c > temp){
                temp = c;}}
    }
    printf("%d\n",temp);
    return 0;}
