Learn to code from scratch.
Zero to hero, all free.
Flycodx isn't only for DSA. If you've never written a line of code, you start with basic programming problems and a personalized roadmap that guides you — one step at a time — all the way to advanced algorithms and interviews.
Basic programming questions — start at the very beginning
Before any data structures, build real programming fundamentals. Every problem runs in a real compiler (Python, Java, C++, JavaScript, C, Go) with instant feedback.
Variables & data types
Store and use values
Input / Output
Read input, print results
Conditionals
if / else decision making
Loops & patterns
Repeat logic, print patterns
Functions
Reusable blocks of code
Basic math & logic
Numbers, factors, sums
Your personalized programming roadmap
The roadmap on your Flycodx dashboard is a step-by-step learning path tailored to your level — Beginner, Intermediate, or Pro. It picks the right topics in the right order and curates the best problems for each (easiest first), so you always know exactly what to practice next. Click any topic to solve its problems, pick your language, and watch your progress grow.
Programming Fundamentals
Variables, I/O, conditionals, loops, patterns, functions — the absolute basics, in a real compiler.
Core Topics
Arrays, Strings, Hash Maps, Sorting, Searching — the building blocks every coder needs.
Data Structures & Algorithms
Linked Lists, Stacks, Queues, Trees, Graphs, Dynamic Programming — interview-grade DSA.
Contests & Interviews
Live weekly contests, company interview kits, and JD-based prep roadmaps.
