算法4-1.1.28删除重复元素

删除重复元素。修改BinarySearch类中的测试用例来删去排序之后白名单中所有重复元素。

代码

public class Main {
    public static void rank(int[] a, String[] keys, char arg){
        int[] whiteList = new int[]{7,1,4,6,5};
        Arrays.sort(whiteList);
        List<Integer> list = new ArrayList<>();
        for (int i = 0; i < whiteList.length-1; i ++){
            if(whiteList[i] != whiteList[i+1]){
                list.add(whiteList[i]);
            }
        }

        Iterator<Integer> iterator= list.iterator();
        while (iterator.hasNext()){
            System.out.println(iterator.next());
        }
    }
    public static void main(String[] args) {
        rank(a, keys, arg);
    }
}
