Скачать или смотреть LeetCode 2423 - Remove Letter to Equalize Frequency | Simple Python Explanation for Beginners

In this video, we break down LeetCode 2423 – Remove Letter to Equalize Frequency in a simple, beginner-friendly way 🧠.

You’ll see why greedy intuition fails (like “just remove the max frequency letter”) and how to correctly solve it by:

Using Counter to track character frequencies

Trying the removal of each letter once

Checking if all frequencies become equal with len(set(counter.values())) == 1

Handling the classic Python “dictionary changed size during iteration” error using sorted()

This is not about the most optimized hardcore solution - it’s about building the right intuition so you can slowly get comfortable with frequency-based problems and pattern recognition in coding interviews.

If you’re a beginner in LeetCode, Python, or DSA, this is for you.
