What is 'polymorphism' in the context of data structures?

The ability of an object to take on multiple forms in object-oriented programming

The ability of a data structure to store elements of different types

The ability of a single function or method to handle different types of input or arguments

The ability of a data structure to store elements in non-contiguous memory locations

What is the 'avl tree'?

A type of tree that guarantees the height difference between left and right subtrees of any node is at most 1

A type of tree where each node has exactly two children

A type of tree that stores elements in a sorted manner

A type of tree used to implement priority queues

3 / 10

Explain the concept of 'amortized analysis'.

Amortized analysis refers to the analysis of the worst-case time complexity of an algorithm

Amortized analysis refers to the analysis of the average-case time complexity of an algorithm

Amortized analysis refers to the analysis of the average cost of a sequence of operations over time

What is 'Big O notation' used for?

To measure the physical size of data structures

To measure the execution time of algorithms

To analyze and describe the time complexity of algorithms in terms of their input size

5 / 10

What is the purpose of 'dynamic programming'?

To design algorithms that adapt to changing data structures

To design algorithms that are dynamic and can change their behavior

To solve problems by breaking them down into smaller subproblems and storing the solutions to these subproblems to avoid redundant computations

To implement data structures that are capable of dynamic resizing

6 / 10

Explain the concept of 'Dijkstra's algorithm'.

An algorithm used to find the shortest path between two nodes in a graph with non-negative edge weights

An algorithm used to find the longest path between two nodes in a graph with negative edge weights

An algorithm used to find the maximum flow in a network flow graph

An algorithm used to find the Eulerian cycle in a graph

7 / 10

What is a 'priority queue'?

A linear data structure used to store elements in non-contiguous memory locations

A non-linear data structure used to store key-value pairs in a hierarchical manner

A type of queue where each element has a priority associated with it, and the element with the highest priority is dequeued first

A data structure that stores elements in a sorted manner

8 / 10

Explain the concept of 'stack underflow' and 'stack overflow'.

Stack underflow occurs when the stack has more elements than its capacity

Stack underflow occurs when an element is removed from an empty stack

Stack overflow occurs when an element is added to a full stack

Stack overflow occurs when the stack has fewer elements than its capacity

9 / 10

What is the purpose of 'circular queue'?

To implement a Last In First Out (LIFO) behavior

To implement a First In First Out (FIFO) behavior

To implement a queue where the front and rear ends are connected, allowing efficient use of memory

To implement a stack

What is a 'trie' in data structures?

A linear data structure used to store elements in contiguous memory locations

A tree-like data structure used to efficiently store a dynamic set of strings

A data structure used to implement stacks and queues

A non-linear data structure used to store key-value pairs in a hierarchical manner
