Pattern Comparison Pages

Use side-by-side strategy pages when multiple approaches could work. This helps pick the right pattern faster in interviews.

→
Top-Down DP vs Bottom-Up DP
Same recurrence, different execution style and performance profile.
→
Binary Search vs Two Pointers
Both exploit order, but one halves search space while the other shrinks a range.
