Circular Array

Circular Array A circular array treats a fixed-size array as if it wraps around. Indices advance modulo the capacity, so the structure forms a logical ring. You use it when you need constant-time insertions and removals at both ends within a bounded buffer. Problem Maintain a sequence $A$ of capacity $n$ that supports: insert at front and back remove from front and back wrap indices without shifting elements Structure A...
