Solve a practical parsing and inventory tracking challenge reported at GEICO that involves computing available capacities within a structured grid layout. Programmers must ingest reservation data, decode alphanumeric seat coordinates, and calculate remaining open slots against predefined cabin dimensions. This exercise assesses fundamental parsing capabilities and matrix arithmetic. Reading the full problem description and verified solution code requires an active subscription.

This GEICO interview problem requires you to design and implement a core set of operations for a text editor. You'll need to support efficient insertion of characters at specific indices, deletion of character ranges, and retrieval of individual characters. The challenge lies in choosing and implementing a data structure that can handle these dynamic string modifications effectively, ensuring good performance for all operations. This tests your understanding of data structures suitable for mutable sequences. The full problem and model solution require a subscription.
