What does HTML stand for?
HyperText Markup Language
Hyperlink and Text Markup Language
HighText Machine Language
HyperTool Multi Language
HTML stands for HyperText Markup Language, which is the standard markup language for creating web pages. It uses elements represented by tags to structure content and embed resources. HTML is not a programming language but a markup language that browsers interpret to render pages. MDN Web Docs: HTML
Which keyword is used to define a function in JavaScript?
function
def
fun
lambda
In JavaScript, the keyword function is used to declare both named and anonymous functions. It defines a block of code designed to perform a particular task and can be reused. Other languages like Python use def, but JavaScript specifically uses function. MDN Web Docs: Functions
In Git, what command is used to stage changes before committing?
git add
git commit
git stage
git push
The git add command updates the index using the current content found in the working tree, preparing the content staged for the next commit. Without staging, git commit will have nothing to record. After staging, you use git commit to save the snapshot. Official Git Documentation: git-add
Which protocol is commonly used to securely transfer files over the Internet?
SFTP
FTP
HTTP
SMTP
SFTP (SSH File Transfer Protocol) provides secure file transfer capabilities by using SSH to encrypt both commands and data. FTP is unencrypted and insecure, while FTPS adds SSL/TLS encryption to FTP. HTTP and SMTP are for web pages and email, respectively. Wikipedia: SSH File Transfer Protocol
What is the time complexity of binary search on a sorted array?
O(log n)
O(n)
O(n log n)
O(1)
Binary search divides the search interval in half with each step, leading to a logarithmic time complexity of O(log n). It requires the array to be sorted and compares the target to the midpoint element. Each comparison discards half of the remaining elements, so the growth rate is logarithmic. Wikipedia: Binary Search Algorithm
Which HTTP status code indicates that the requested resource was not found on the server?
404
200
302
500
HTTP 404 Not Found indicates that the server could not find the requested resource. This status code is commonly returned when a URL is incorrect or the resource has been removed. A 200 status means success, 302 indicates redirection, and 500 is a server error. MDN Web Docs: 404 Not Found
In CSS, which property is used to change the text color of an element?
color
text-color
font-color
foreground-color
The CSS color property sets the color of text content in an element. Other properties such as background-color change the background, but color specifically targets text. It accepts color names, hex codes, RGB, and other color formats. MDN Web Docs: color
What does SQL stand for?
Structured Query Language
Sequential Query Language
Simple Query Logic
Standard Query Language
SQL stands for Structured Query Language and is used to communicate with and manipulate relational databases. It allows users to query, insert, update, and delete database records. SQL is standardized by ANSI and ISO, though many database systems add proprietary extensions. Wikipedia: SQL
Which sorting algorithm has an average time complexity of O(n log n) and is stable?
Merge Sort
Quick Sort
Heap Sort
Selection Sort
Merge Sort is a stable, divide-and-conquer sorting algorithm with an average and worst-case time complexity of O(n log n). It splits the list in half, sorts each half, and then merges the sorted halves. Quick Sort is not stable in its typical in-place implementation, and Heap Sort is also not stable. Wikipedia: Merge Sort
In RESTful API design, which HTTP method is considered idempotent?
PUT
POST
CONNECT
TRACE
PUT is idempotent because making the same request multiple times results in the same server state. GET, DELETE, and PUT are idempotent, while POST is not because it may create multiple resources. Idempotent methods help clients safely retry requests without unintended effects. RESTful API Tutorial: Idempotency
What is the primary purpose of the SOLID principles in software development?
To improve code maintainability and flexibility
To enforce strict typing in dynamic languages
To speed up compilation times
To guarantee zero runtime errors
The SOLID principles are a set of five design guidelines intended to make software designs more understandable, flexible, and maintainable. They address class design, dependencies, and responsibilities to reduce coupling and increase cohesion. They do not enforce typing or eliminate all runtime errors. Wikipedia: SOLID (object-oriented design)
In Java, what does the 'volatile' keyword guarantee when applied to a variable?
Visibility of changes across threads immediately
Atomicity of compound operations
That the variable is stored on CPU cache only
That the variable cannot be garbage collected
The volatile keyword in Java ensures that reads and writes to a variable go directly to main memory, making changes visible to all threads immediately. It does not guarantee atomicity of compound operations like increment. It also prevents certain compiler optimizations that cache variables in registers. Oracle Java Concurrency Tutorial
According to the CAP theorem for distributed systems, which combination is impossible to guarantee simultaneously?
Consistency, Availability, and Partition Tolerance all at once
Consistency and Availability without Partition Tolerance
Availability and Partition Tolerance without Consistency
Consistency and Partition Tolerance without Availability
The CAP theorem states that a distributed data store cannot simultaneously provide all three guarantees: Consistency, Availability, and Partition Tolerance. You must choose two at the expense of the third. This is fundamental in distributed architecture design and trade-off analysis. Wikipedia: CAP theorem
When implementing a lock-free data structure, which atomic operation is most commonly used to avoid race conditions?
Compare-and-swap (CAS)
Test-and-lock
Mutex lock
Semaphore wait
Compare-and-swap (CAS) is a hardware-supported atomic instruction that reads a memory location, compares it to an expected value, and if they match, updates it. This allows lock-free algorithms to manage concurrency without heavy locking overhead. Other mechanisms like mutex locks are not lock-free. Wikipedia: Compare-and-swap

Cheat Sheet

  1. Core Data Structures for Trivia Software -

    Efficient question storage is key in a coding trivia quiz: use arrays for ordered traversal and hash tables for O(1) lookups of questions and user scores. For example, a Python dict like {'Q1': 'What is polymorphism?'} gives instant access by key. Mnemonic: "Hash it, fetch it!" (Source: Cormen et al., Introduction to Algorithms).

  2. Designing RESTful APIs for a Developer Trivia Quiz -

    A well-structured API uses GET for retrieving questions, POST for submissions, and ensures idempotency on updates (PUT). Example endpoint: GET /api/questions?page=1&category=OOP, following RFC 7231 conventions. Always include clear status codes and JSON schemas (Source: IETF RFC 7231, OWASP API Security).

  3. Implementing Randomization with Fisher-Yates Shuffle -

    To deliver unpredictable question orders, apply the Fisher-Yates algorithm: for i from n−1 down to 1, swap elements[i] with elements[random(0,i)]. This ensures uniform distribution in your software trivia engine. Remember the Durstenfeld improvement for in-place efficiency (Source: R. Durstenfeld, "Algorithm 235").

  4. User Experience Principles for a Software Developer Quiz -

    Keep interfaces clean and use progressive disclosure: start with one question per screen and reveal hints only on demand to avoid cognitive overload. Ensure responsive design for desktop and mobile so developers can quiz anywhere. Follow Nielsen Norman Group's 10 usability heuristics for intuitive navigation (Source: Nielsen Norman Group).

  5. Performance Optimization and Caching Strategies -

    Minimize database hits in your trivia software by caching popular question sets in Redis or Memcached, using a TTL to refresh stale data. Performance rule of thumb: Total latency ≈ compute time + I/O time, so reduce T_io with in-memory caching. For deeper techniques, see ACM's best practices on scalable web services (Source: ACM Digital Library).
