# how to solve this with only one List?

Jun 19 2022 11:07 AM

Hi

yesratday, i posted a question about List<T> in a simulation of (soccer) matches. Each team plays against the orher teams . The winner gets 3 points and only 1 point when even.

I got an answer from Ricardo Rigutini. He suggested to use a class and only one List instead of three. I tried his suggestion but i'm stuck when i have to give points to the winner of each match (points[i] += 3;). I wonder to do that without other List.

I show you the code so far ... Thansk for help.

using System;
using System.Collections.Generic;
using System.Linq;
class Oef16
{
private class TeamScore
{
public string TeamName { get; set; }
public int Score { get; set; }

public TeamScore(string name)
{
TeamName = name;
}

public override string ToString()
{
if (Score < 10)
return "0" + Score + " " + TeamName;
else
return Score + " " + TeamName;
}
}

public static void Main()
{
int match;
Random rand = new Random();
List<TeamScore> teams = new List<TeamScore>
{ new TeamScore("team A"), new TeamScore("team B"), new TeamScore("team C")};

List<int> points = new List<int> { };
for (int i = 0; i < teams.Count; i++)

for (int i = 0; i <= teams.Count - 1; i++)
{
for (int j = i + 1; j <= teams.Count - 1; j++)
{
match = rand.Next(1, 4); // 1 = team A wins, 2 = team B wins, 3 = even
switch (match)
{
case 1:
points[i] += 3;
break;
case 2:
points[j] += 3;
break;
default:
points[i] += 1;
points[j] += 1;
break;
}
}
}
int m = points.Max();
int p = points.IndexOf(m);

Console.WriteLine("Final ranking: the winner is " + teams[p] + " with " + points[p] + " points.");

List<string> teampoint = new List<string> { };
for (int i = 0; i < teams.Count; i++)

for (int i = 0; i <= teams.Count - 1; i++)
{
if (points[i] < 10)
teampoint[i] = "0" + points[i] + " " + teams[i];
else
teampoint[i] = points[i] + " " + teams[i];
}

teams = teams.OrderBy(x => x.Score).ToList();
teams.Reverse();

foreach (string i in teampoint)
Console.WriteLine(i);
}
