Problem:
Small, Large, or Equal

Write a program which prints small/large/equal relation of given two integers a and b.

Input

Two integers a and b separated by a single space are given in a line.

Output

For given two integers a and b, print

a < b

if a is less than b,

a > b

if a is greater than b, and

a == b

if a equals to b.

Constraints

-1000 ≤ a, b ≤ 1000

Sample Input 1

1 2

Sample Output 1

a < b

Sample Input 2

4 3

Sample Output 2

a > b

Sample Input 3

5 5

Sample Output 3

a == b

Solution in C# (judge verdict: Wrong Answer)

using System;

namespace AizuOnlineJudge
{
    class Program
    {
        static void Main(string[] args)
        {
            var array = Converter(Console.ReadLine());
            Console.WriteLine(Calc(array));
        }

        static int[] Converter(string str)
        {
            var array = str.Split(' ');
            return Array.ConvertAll(array, int.Parse);
        }

        static string Calc(int[] array)
        {
            string symbol;
            var sign = Math.Sign(array[0] - array[1]);
            switch (sign)
            {
                case 1:
                    symbol = ">";
                    break;
                case -1:
                    symbol = "<";
                    break;
                default:
                    symbol = "==";
                    break;
