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.
Example 1:
Input: [3,2,3] Output: 3
Example 2:
Input: [2,2,1,1,1,2,2] Output: 2
public int majorityElement(int[] nums) {//my int re = 0; int num = 0; for (int i = 0; i < nums.length; i++) { if(0==num){ re = nums[i]; num++; } else{ if(nums[i]==re){ num++; } else{ num--; } } } return re; }
