循环赛排序

小组搞个台球比赛，什么都写代码实现真是个好习惯：

var players = [
    'Lion',
    'Miles',
    'Mark',
    'Purk',
    'Kevin',
    'Collen',
    'Victor'
];

var playlist = [];

for (var i = 0; i < players.length; i++) {
    for (var j = i + 1; j < players.length; j++) {
        playlist.push(players[i] + '  --  ' + players[j])
    }
}

playlist.sort(function() {
    return Math.random() > 0.5? - 1: 1;
});

for (var i =0; i<playlist.length; i++) {
    console.log(i+'. '+playlist[i]);
};
