FAQ

    What is an algorithm?
  • An algorithm is a step-by-step procedure or formula for solving a problem. It consists of a sequence of instructions that are executed in a specific order to achieve a desired outcome.
  • What are the characteristics of a good algorithm?
  • A good algorithm should be clear and unambiguous, have well-defined inputs and outputs, be efficient in terms of time and space complexity, be correct (produce the expected output for all valid inputs), and be general enough to solve a broad class of problems.
  • What is the difference between a greedy algorithm and a dynamic programming algorithm?
  • A greedy algorithm makes a series of choices, each of which looks best at the moment, without considering the bigger picture. Dynamic programming, on the other hand, solves problems by breaking them down into simpler subproblems and storing the results to avoid redundant calculations.
  • What is Big O notation?
  • Big O notation is a mathematical representation used to describe the upper bound of an algorithm's time or space complexity, providing an estimate of the worst-case scenario as the input size grows.
  • What is a recursive algorithm?
  • A recursive algorithm solves a problem by calling itself with smaller instances of the same problem until it reaches a base case that can be solved directly.
  • What is the difference between depth-first search (DFS) and breadth-first search (BFS)?
  • DFS explores as far down a branch as possible before backtracking, using a stack data structure (often implemented via recursion). BFS explores all neighbors at the present depth prior to moving on to nodes at the next depth level, using a queue data structure.
  • What are sorting algorithms, and why are they important?
  • Sorting algorithms arrange elements in a particular order (ascending or descending). They are important because many other algorithms rely on sorted data to function correctly or efficiently.
  • How does binary search work?
  • Binary search works by repeatedly dividing a sorted array in half, comparing the target value to the middle element, and narrowing down the search interval until the target value is found or deemed absent.
  • What is an example of a divide-and-conquer algorithm?
  • Merge Sort is an example of a divide-and-conquer algorithm. It divides an array into two halves, recursively sorts each half, and then merges the sorted halves back together.
  • What is memoization in algorithms?
  • Memoization is an optimization technique used to speed up algorithms by storing the results of expensive function calls and reusing them when the same inputs occur again.
  • What is the traveling salesman problem (TSP)?
  • The TSP is an optimization problem that seeks to find the shortest possible route that visits each city exactly once and returns to the origin city. It is NP-hard, meaning it is computationally challenging to solve optimally for large numbers of cities.
  • What is an approximation algorithm?
  • An approximation algorithm finds near-optimal solutions to optimization problems within a specified factor of the optimal solution, often used when exact solutions are computationally infeasible.
  • How do hashing algorithms work?
  • Hashing algorithms take input data and produce a fixed-size string of characters, which appears random. They are commonly used in data structures like hash tables for fast data retrieval.
  • What is graph traversal in algorithms?
  • Graph traversal refers to visiting all nodes in a graph in some systematic way. Common methods include depth-first search (DFS) and breadth-first search (BFS).
  • Why are algorithms important in computer science?
  • Algorithms are fundamental to computer science because they provide systematic methods for solving problems efficiently and effectively across various domains, from simple tasks like sorting numbers to complex tasks like machine learning and cryptography.
