Top 5 Mistakes to Avoid When Learning Data Structures & Algorithms βπ§
1οΈβ£ Memorizing Without Understanding
Just cramming code isnβt effective. Focus on why a solution works, not just how. Understanding concepts beats rote memorization.
2οΈβ£ Ignoring Time & Space Complexity
Big-O notation matters. Skipping it risks writing code that works but performs poorly in real-life large data scenarios.
3οΈβ£ Not Practicing Enough
Reading solutions isn't the same as solving problems. You must struggle, debug, and iterate for genuine learning and skill-building.
4οΈβ£ Avoiding Hard Problems
Sticking to easy problems limits growth. Challenge yourself with medium and hard problems to improve problem-solving skills.
5οΈβ£ Skipping Real-World Application
Donβt just solve abstract problems. Apply DSA concepts to real projects like optimizing search, sorting data, or efficient API building to see practical impact.

Top DSA Interview Questions with Answers: Part-1 π§
1. What is a Data Structure?
A data structure is a way to organize, store, and manage data efficiently so it can be accessed and modified easily. Examples: Arrays, Linked Lists, Stacks, Queues, Trees, Graphs.
2. What are the different types of data structures?
β’ Linear: Arrays, Linked Lists, Stacks, Queues
β’ Non-linear: Trees, Graphs
β’ Hash-based: Hash Tables, Hash Maps
β’ Dynamic: Heaps, Tries, Disjoint Sets
3. What is the difference between Array and Linked List?
β’ Array: Fixed size, index-based access (O(1)), insertion/deletion is expensive
β’ Linked List: Dynamic size, sequential access (O(n)), efficient insertion/deletion at any position
4. How does a Stack work?
A Stack follows LIFO (Last In, First Out) principle.
β’ Operations: push() to add, pop() to remove, peek() to view top
β’ Used in: undo mechanisms, recursion, parsing
5. What is a Queue? Difference between Queue and Deque?
A Queue follows FIFO (First In, First Out).
β’ Deque (Double-Ended Queue): Allows insertion/removal from both ends.
β’ Used in scheduling, caching, BFS traversal.
6. What is a Priority Queue?
A type of queue where each element has a priority.
β’ Higher priority elements are dequeued before lower ones.
β’ Implemented using heaps.
7. What is a Hash Table and how does it work?
A structure that maps keys to values using a hash function.
β’ Allows O(1) average-case lookup, insert, delete.
β’ Handles collisions using chaining or open addressing.
8. What is the difference between HashMap and HashSet?
β’ HashMap: Stores key-value pairs
β’ HashSet: Stores only unique keys (no values)
Both use hash tables internally.
9. What are Trees? Explain Binary Tree.
A tree is a non-linear structure with nodes connected hierarchically.
β’ Binary Tree: Each node has at most 2 children (left, right).
Used in hierarchical data, parsers, expression trees.
10. What is a Binary Search Tree (BST)?
A special binary tree where:
β’ Left child < Node < Right child
β’ Enables fast lookup, insert, and delete in O(log n) (average case).
Maintains sorted structure.

Top DSA Interview Questions with Answers: Part-2 π§
11. What is the difference between BFS and DFS?
- BFS (Breadth-First Search): Explores neighbors first (level by level). Uses a queue. β‘οΈ
- DFS (Depth-First Search): Explores depth (child nodes) first. Uses a stack or recursion. β¬οΈ
Used in graph/tree traversals, pathfinding, cycle detection. π³π
12. What is a Heap?
A binary tree with heap properties:
- Max-Heap: Parent β₯ children πΌ
- Min-Heap: Parent β€ children π½
Used in priority queues, heap sort, scheduling algorithms. β°
13. What is a Trie?
A tree-like data structure used to store strings. π²
Each node represents a character.
Used in: autocomplete, spell-checkers, prefix search. π‘
14. What is a Graph?
A graph is a collection of nodes (vertices) and edges. π
- Can be directed/undirected, weighted/unweighted.
Used in: networks, maps, recommendation systems. πΊοΈ
15. Difference between Directed and Undirected Graph?
- Directed: Edges have direction (A β B β B β A) β‘οΈ
- Undirected: Edges are bidirectional (A β B) βοΈ
Used differently based on relationships (e.g., social networks vs. web links).
16. What is the time complexity of common operations in arrays and linked lists?
- Array: π’
- Access: O(1)
- Insert/Delete: O(n)
- Linked List: π
- Access: O(n)
- Insert/Delete: O(1) at head
17. What is recursion?
When a function calls itself to solve a smaller subproblem. π
Requires a base case to stop infinite calls.
Used in: tree traversals, backtracking, divide & conquer. π³π§©
18. What are base case and recursive case?
- Base Case: Condition that ends recursion π
- Recursive Case: Part where the function calls itself β‘οΈ
Example:
19. What is dynamic programming?
An optimization technique that solves problems by breaking them into overlapping subproblems and storing their results (memoization). πΎ
Used in: Fibonacci, knapsack, LCS. π
20. Difference between Memoization and Tabulation?
- Memoization (Top-down): Uses recursion + caching π§
- Tabulation (Bottom-up): Uses iteration + table π
Both store solutions to avoid redundant calculations.
