Problem Statement

You are given two integers A and B.
Find the largest value among A+B, A-B and A \times B.

Constraints

-1000 \leq A,B \leq 1000

All values in input are integers.

Input

Input is given from Standard Input in the following format:

A B

Output

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include<stdio.h>
int main()
{
    int A,B,x,y,z;

    scanf("%d %d",&A,&B);

    x=A+B;
    y=A-B;
    z=A*B;

    if(x>y && x>z)
    {
        printf("%d\n",x);
        printf("%d + %d = %d,%d - %d = %d,%d * %d = %d The largest is %d.\n",A,B,x,A,B,y,A,B,z,x);

    }
    else if(y>x && y>z)
    {
        printf("%d\n",y);
        printf(" The largest is %d - (%d) = %d.\n",A,B,y);
    }

    else
    {

        printf("%d\n",z);
    }




    return 0;
