Algorithms are step-by-step instructions used to solve problems, while data structures are containers to organize and store data efficiently.
Name an example of an algorithm.
An example of an algorithm is finding the factorial of a number using a loop.
What is the difference between an array and a linked list?
An array stores a fixed-size sequential collection of elements, while a linked list organizes data using nodes that point to the next element in the list.
What are the advantages of using a stack data structure?
The advantages of using a stack include its ability to efficiently manage function calls, support undo operations, and perform depth-first search algorithms.
What is a binary search tree?
A binary search tree is a data structure that organizes elements in a hierarchical manner, where the left child node is always smaller than the parent node and the right child node is always larger.
Explain the concept of time complexity in algorithms.
Time complexity measures the performance of an algorithm by analyzing the amount of time it takes to execute as the input size increases.
What is the purpose of a hash table?
A hash table is used to store and retrieve data quickly, providing constant-time average case performance for key-value operations.
What is the difference between a queue and a stack?
A queue is a data structure that follows the First-In-First-Out (FIFO) principle, while a stack follows the Last-In-First-Out (LIFO) principle.
What is the purpose of sorting algorithms?
Sorting algorithms are used to arrange data in a specific order, such as ascending or descending, to facilitate searching and efficient data retrieval.
What is a linear search algorithm?
A linear search algorithm sequentially checks each element in a list until the desired target is found or the end of the list is reached.
Explain the concept of recursion.
Recursion is a programming technique where a function calls itself to solve a smaller version of the same problem, ultimately reaching a base case to terminate the process.
What is a graph data structure?
A graph data structure is a collection of nodes (vertices) connected by edges, representing relationships or connections between various entities.
What is the advantage of using a tree data structure?
Tree data structures provide efficient storage and retrieval operations, enabling faster search, insertion, and deletion of elements compared to other data structures.
What is a priority queue?
A priority queue is a data structure that assigns a priority value to each element and allows elements to be retrieved in order of their priority.
Explain the concept of dynamic programming.
Dynamic programming is an optimization technique that breaks down complex problems into overlapping subproblems and stores their solutions to avoid redundant calculations.
