Didn't test but would be something like this.

PHP Code:

    int aliveCTCount;
    int aliveTCount;
    int lastTClient;
    
    for (int client = 1; client <= MaxClients; client++)
    {
        if (!IsClientInGame(client))
            continue;
        
        if (IsFakeClient(client))
            continue;
        
        if (!IsPlayerAlive(client))
            continue;
        
        if (GetClientTeam(client) == CS_TEAM_CT)
        {
            aliveCTCount++;
        }
        else if (GetClientTeam(client) == CS_TEAM_T)
        {
            aliveTCount++;
            lastTClient = client;
        }
    }
    
    if (aliveCTCount == 1 && aliveTCount == 1)
    {
        PerformBeacon(lastTClient) //Your logic here
    }
