20+ Autodesk Interview Questions and Answers

Program to find a character with same occurrences count in a string in a single iteration.

• Iterate through the string and keep track of character occurrences in a hashmap.

• Check for characters with the same occurrence count in the hashmap.

• Return the first character found with the same occurrence count.

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.

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

Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as the same type.

• Polymorphism is a fundamental concept in object-oriented programming.

• It enables code reusability and flexibility.

• Polymorphism can be achieved through method overriding and method overloading.

• Example: A parent class Animal can have multiple child classes like Dog, Cat, and Bird. They can all be treated as Animal objects.

• Polymorphism allows for w...read more

Static polymorphism refers to the ability of a programming language to select the appropriate function or method at compile-time.

• Static polymorphism is achieved through function overloading or operator overloading.

• It allows different functions with the same name but different parameters to be called based on the arguments provided.

• The selection of the appropriate function is determined at compile-time, based on the static type of the object or arguments.

• Static polymorphism is...read more

Dynamic polymorphism is the ability of an object to take on many forms based on the context it is used.

• It allows objects of different classes to be treated as objects of a common superclass.

• It is achieved through method overriding and virtual functions.

• Example: A superclass 'Animal' with subclasses 'Dog' and 'Cat'. Both can be treated as 'Animal' objects.

var is function scoped, let is block scoped in JavaScript.

• var is function scoped, let is block scoped

• var can be redeclared, let cannot be redeclared
