Autodesk Software Developer Interview Questions and Answers

A linked list is a data structure where each element points to the next element in the sequence.

• Linked list is stored in memory as nodes, where each node contains data and a reference to the next node.

• Examples of linked-list include a singly linked list, doubly linked list, and circular linked list.

• In a singly linked list, each node points to the next node. In a doubly linked list, each node points to both the next and previous nodes.

Return a string containing the first occurrence of characters in the input string.

• Create an empty string to store the result.

• Iterate through each character in the input string.

• If the character is not already in the result string, add it to the result string.

• Return the result string.

One of the hardest DSA questions I have done involved implementing a complex graph traversal algorithm.

• The question required understanding of graph data structures and algorithms.

• I had to implement a depth-first search or breadth-first search algorithm.

• The question may have involved finding the shortest path in a weighted graph.

• I had to consider edge cases and optimize the algorithm for efficiency.

ML models are built by collecting and preparing data, selecting a model, training the model on the data, and evaluating its performance.

• Collect and prepare data by cleaning, transforming, and encoding it

• Select a model based on the problem at hand (e.g. regression, classification, clustering)

• Train the model using algorithms like linear regression, decision trees, or neural networks

• Evaluate the model's performance using metrics like accuracy, precision, recall, or F1 score

Arrays store elements in contiguous memory locations, while linked lists store elements in nodes with pointers to the next node.

• Arrays have fixed size, while linked lists can dynamically grow or shrink.

• Accessing elements in arrays is faster (O(1)), while accessing elements in linked lists is slower (O(n)).

• Inserting or deleting elements in arrays can be inefficient, as it may require shifting elements, while in linked lists it can be done in constant time.

• Example: Array - ['ap...read more

OS stands for Operating System. It is a software that manages computer hardware and provides services for computer programs.

• OS is the software that acts as an intermediary between computer hardware and user applications.

• It manages computer resources such as memory, processors, devices, and file systems.

• Examples of popular operating systems include Windows, macOS, Linux, and Android.
