169. Majority Element

Easy

Topics

Companies

Given an array nums of size n, return the majority element.

The majority element is the element that appears more than ⌊n / 2⌋ times. You may assume that the majority element always exists in the array.

Example 1:

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

Example 2:

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

Constraints:

  • n == nums.length
  • 1 <= n <= 5 * 10<sup>4</sup>
  • -10<sup>9</sup> <= nums[i] <= 10<sup>9</sup>

Follow-up: Could you solve the problem in linear time and in O(1) space?
