采用多种算法，模拟摇奖：从1-36中随机抽出8个不重复的数字

    public static void main(String[] args) 
    {
        Random ran = new Random();
        int[] arr=new int[8];       
        for(int i =0;i<8;i++)
        {
            arr[i]=ran.nextInt(36);
            for(int j=0;j<i;j++)
            {
                if(arr[i]==arr[j])
                {
                    i--;               
                }                
            }
