[Extremo]

Well, if you don't mind using third party includes, using this: https://sampforum.blast.hk/showthread.php?tid=343172
you could outperform the code above at the cost of memory.

pawn Code:

new RichList[MAX_PLAYERS][2];

stock FindRichest()
{
     RichList = {{0,0}...}; // Reset the array in case you only want online players to show up, u probs gotta rely on a loop there.. this doesn't work I am sure but you get the point.
    foreach(new p : Player) // obv if u dont have foreach, yanno
    {
        RichList[p][0] = GetPlayerMoney(p);
        RichList[p][1] = p;
    }
    SortDeepArray(RichList, 0);
    // richest are:
    RichList[200][1], RichList[199][1], RichList[198][1], RichList[197][1]
}

The code above is more or less pseudo code and probably doesn't work the way I wrote it but I am sure you get the picture =).

Regards.
