LeetCode 347 | Top K Frequent Elements | Brute Force to Optimal | C++ | NeetCode 150 - Problem 4

Описание: Hey everyone,
I’m a final-year IT undergraduate from VJTI Mumbai, and this video marks the beginning of my NeetCode 150 problem-solving journey.

In this video, I solve LeetCode 347 – Top K Frequent Elements using C++. I start with a straightforward brute force approach and then transition to the optimal solution. The focus is not just on writing code, but on understanding why each approach works, making it beginner-friendly for anyone learning DSA.

This playlist is my way of staying consistent with problem-solving, revising core data structures and algorithms for interviews, and helping others who are preparing alongside me.

What I cover in this video:
Clear explanation of the problem
Brute force approach with detailed thought process
Why the brute force solution is inefficient
Optimized solution using a hash set
Time and space complexity analysis
Clean and readable C++ implementation


Programming Language Used:
C++

Feel free to connect, share feedback, or discuss DSA and interview preparation.
