This Nuro coding challenge focuses on data processing from structured log entries. You are provided with a collection of log lines, each formatted to contain various pieces of information separated by commas. The primary objective is to accurately extract a specific data point—the error code—from each line. After extraction, you must tally the occurrences of every unique error code found. Finally, the aggregated counts should be presented as a sorted list of pairs, where each pair consists of an error code and its total frequency. This problem tests string manipulation, data aggregation, and sorting skills. The full problem description and a model solution are available with a subscription.

This Nuro interview challenge explores advanced graph traversal techniques, asking engineers to find the shortest path across a grid populated by impassable barriers. The catch is that the traversal agent possesses a limited ability to clear obstacles along the way, adding a layer of state management to standard pathfinding algorithms like breadth-first search. Candidates must efficiently track remaining clearances alongside spatial coordinates to avoid redundant states and locate the target destination. The complete problem statement and an optimal model solution are available exclusively with a paid subscription.
