Problem: Majority Element

easy
15 min
Explore how to determine the majority element in an array where an element appears more than half the time. This lesson helps you understand the problem constraints and implement a solution with O(n) time and O(n) space complexity.

Statement

Given an array, nums, having nn integers, return the majority element. An element will be considered a majority element if it occurs more than n/2⌊n / 2⌋ times in the array.

Note: It is safe to assume that the majority element always exists in the array.

Constraints

  • n==n == nums.length
  • 1n31031\leq n\leq 3 * 10^3
  • 104−10^4 \leq nums[i] 104\leq10^4
