Understand the problem
Restate the problem precisely. Interviewers reward candidates who pause, define the contract, and name the guarantees before coding.
Problem statement
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
nums = [3, 2, 3] → 3
Constraints
n == nums.length · 1 ≤ n ≤ 5 × 10⁴ · −10⁹ ≤ nums[i] ≤ 10⁹
