Binary Search Patterns: Five Variants Every Senior Engineer Knows

TLDR: Binary search has five patterns beyond the classic "find the target": leftmost position, rightmost position, rotated array search, minimum in rotated array, and 2D matrix search. The root of eve

Why Binary Search Is Preferred Over Ternary Search Despite log₃(n)

Algorithms rarely fail because they are incorrect.They fail because assumptions that look valid mathematically do not survive contact with real machines. Ternary search is a classic example. Yet binary search remains the default — in standard librari...

Binary Search

Binary Search is used on sorted Arrays. 🧩 Binary Search works if : There exists a monotonic relationship in your search space —that is, a point divides the domain into two consistent halves: The left half satisfies one condition (e.g., false), Th...
