In this video, we solve the Majority Element in an Array problem using Java.
This is a very common DSA interview question explained step by step.
Problem Statement:
Given an array of integers, find the element that appears more than n/2 times.
If no such element exists, return -1.
Examples:
Input: [2, 2, 1, 1, 2, 2, 2]
Output: 2
Input: [1, 2, 3]
Output: -1
Approaches Explained:
Brute force approach
Optimized approach using Moore’s Voting Algorithm
Time Complexity: O(n)
Space Complexity: O(1)
Java implementation with dry run
This problem is frequently asked in:
Coding interviews
DSA rounds
FAANG-level array questions
