๐งต This One Pattern Silently Solves Some of the Hardest Array Problems in Coding Interviews
Most people memorize solutions for:
> Two Sum
> 3Sum
> Container With Most Water
> Palindrome checks
> Sorted Squares
Top candidates notice they're all variations of the SAME pattern.
Once this clicks, array problems start feeling predictable instead of random.
Hereโs the simplest explanation of the Converging Two Pointers technique๐
๐ The Biggest Insight
The pattern works because:
> Sorted order gives directional certainty.
> You KNOW which pointer to move.
> Thatโs what eliminates unnecessary comparisons.
> And thatโs why itโs so efficient.
