Majority Element II

---

Given an integer array of size n, find all elements that appear more than ⌊ n/3 ⌋ times.

 

Example 1:

Input: nums = [3,2,3]
Output: [3]

Example 2:

Input: nums = [1]
Output: [1]

Example 3:

Input: nums = [1,2]
Output: [1,2]

 

Constraints:

• 1 <= nums.length <= 5 * 104
• -109 <= nums[i] <= 109
