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()
{
    int n,a,b,i,j,sum,min,mult;

        scanf("%d%d",&a,&b);

        sum=a+b;
        min=a-b;
        mult=a*b;
        if(sum>=min && sum>=mult)
        {
            printf("%d",sum);
        }
        else if(min>=sum && min>=mult)
        {
                       printf("%d",min);
        }
        else if(mult>=sum && mult>=min)
        {
                       printf("%d",mult);
        }
        printf("\n");
