Single Number III

 
阅读更多


解题思路:该题利用一个集合存储遍历的数字,如何初始该集合中没有则加入,有的话则删除,最后集合里面的数字,即是所要求的。

Java代码实现

public class Solution {
   public int[] singleNumber(int[] nums) {
        Set set=new HashSet();
        for(int i=0;i<nums.length;i++){
        	if(!set.contains(nums[i])) set.add(nums[i]);
        	else set.remove(nums[i]);
        }
        int [] re=new int[set.size()];
        Iterator<Integer> it=set.iterator();
        int i=0;
        while(it.hasNext()){
        	re[i++]=it.next();
        }
        //System.out.print(re);
        return re;
        
    }
}
