04. Remove Duplicates II - Leetcode 80 🔥 2 Ultra-Clean Approaches | Ace Two-Pointer Logic Fast

In this video of the LeetCode Top Interview 150 series, we deep-dive into Question #4: Remove Duplicates from Sorted Array II.

You’ll see two production-grade solutions:
⚡ Optimized Two-Pointer Strategy (in-place, O(n))
⚡ Sorting-Driven Deduplication (simple, intuitive approach)

Both implementations leverage clean pointer choreography, algorithmic precision, and interview-ready patterns that scale in real-world engineering workflows.

Whether you're prepping for FAANG or leveling up your data-structure mindset, this walkthrough equips you with future-proof logic and clear mental models. 🚀
