Java for LeetCode 169 Majority Element

Given an array of size n, find the majority element. The majority element is the element that appears more than ⌊ n/2 ⌋ times.

You may assume that the array is non-empty and the majority element always exist in the array.

解题思路:

编程之美P130(寻找发帖水王)原题,如果删除两个不同的num,那么剩下的num,最多的元素依旧出现多于⌊ n/2 ⌋ times

JAVA实现如下:

	public int majorityElement(int[] nums) {
	    LinkedList<Integer> list=new LinkedList<Integer>();
	    for(int num:nums){
	    	if(list.isEmpty())
	    		list.add(num);
	    	else if(num==list.getLast())
	    		list.add(num);
	    	else list.remove(list.size()-1);	
	    }
	    return list.get(0);
	}
