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,c,d,e;
    scanf("%d%d",&a,&b);
    c=a+b;
    d=a-b;
    e=a*b;
    if(c>d && c>e){
        printf("%d\n",c);
        printf("The largest number among A+B=%d, A-B=%d, and AxB=%d is %d\n",c,d,e,c);
    }
    else if(d>c && d>e){
        printf("%d\n",d);
        printf("The largest number among A+B=%d, A-B=%d, and AxB=%d is %d\n",c,d,e,d);
    }
    else if(e>c && e>d){
        printf("%d\n",e);
        printf("The largest number among A+B=%d, A-B=%d, and AxB=%d is %d\n",c,d,e,e);
    }
    return 0;
