Why does this C# code throw an NZEC error? (For TLG problem)

using System;
using System.Collections.Generic;

public class GameLeadProblem
{
    static void Main()
    {
        int rounds = Int32.Parse(Console.ReadLine());
        List<int> round_list = new List<int>();
        int winner = 0;


        for (int i = 0; i < rounds; i++)
        {
            string[] list = (Console.ReadLine()).Split();
            round_list.Add(Int32.Parse(list[0]) - Int32.Parse(list[1]));
        }

        round_list.Sort();
        if (round_list[0] < 0)
        {
            if ((round_list[0] * -1) > round_list[-1])
            {
                winner = 2;
                Console.WriteLine("{0}", winner + "{0}", (round_list[0] * -1));
            }
            else
            {
                winner = 1;
                Console.WriteLine("{0}", winner + "{0}", (round_list[-1]));
            }
        }

    }
}
