FFA Anyone?

I'm looking for a hand to write a small section of code (and possibly help me finish the mod if you're up to it).

Basically I'm stuck on trying to get players assigned to a suitable team for a 1 player per team gamemode.

What I'm trying to accomplish:

-get the number of teams
-get the number of players on each team
-get the lowest team number that has no players
-if there is only one team that already has one player, add a new team with the lowest possible team number
(ex: if team 2 exists add team 0 ex2: if team 0 exists add team 1)
-return "team" where team = the lowest team number with 0 players
-on respawn, assign the player to the same team number
-on nextmap, assign the player to a new team (for variety)

Example:

4 players are playing.

Blue (team 0), red (team 1), green (team 2), and purple (team 3) respectively.

If blue and green both leave, and another player joins, I want him to be assigned to blue team, not green or orange.

Here is the section of code from Shiprekt that I was looking at. It's all greek to me, I've been piecemealing things together from the beginning. I've been burning a lot of time copy-pasting when I'm pretty sure I could have finished a long time ago if I just swallowed my pride and asked for help...

Code:

Random _teamrandom(0x7ea177);

s32 getRandomMinimumTeam(CRules@ this, const int higherThan = -1)
{
    const int teamsCount = this.getTeamsNum();
    int[] playersperteam;
    for(int i = 0; i < teamsCount; i++)
        playersperteam.push_back(0);

    //gather the per team player counts
    const int playersCount = getPlayersCount();
    for(int i = 0; i < playersCount; i++)
    {
        CPlayer@ p = getPlayer(i);
        s32 pteam = p.getTeamNum();
        if(pteam >= 0 && pteam < teamsCount)
        {
            playersperteam[pteam]++;
        }
    }

    //calc the minimum player count
    int minplayers = 1000;
    for(int i = 0; i < teamsCount; i++)
    {
        if (playersperteam[i] < higherThan)
            playersperteam[i] = 1000;
        minplayers = Maths::Min(playersperteam[i], minplayers);
    }

    //choose a random team with minimum player count
    s32 team;
    do {
        team = _teamrandom.NextRanged(teamsCount);
    } while(playersperteam[team] > minplayers);

    return team;
}

If you're interested in helping, you can post here or PM me. If you've played the earlier versions of this mode, you'll know why I want to finish it so badly. It's effing fun!
