Problem: Majority Element

Medium
30 min
Explore how to find the majority element in an integer array where it appears more than half the length of the array. Learn to implement an optimal O(n) time and O(n) space solution, enhancing your algorithmic efficiency and problem-solving skills.

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
