Four Levels. A Clear Path from Beginner to Placement-Ready.

Problems are categorized by difficulty — not randomly mixed. Students progress through a structured path, building confidence at each level before moving to the next. Each level maps to a stage in placement preparation.

BEGINNERLevel 1 — Foundations

170 problems

Programming basics: syntax, loops, conditionals, simple array operations, string manipulation, and basic math. Where every student starts — building the habit of writing complete programs from scratch to master fundamental logic

Loops Conditionals Arrays Strings Basic Math Sorting Searching Pattern Printing

INTERMEDIATELevel 2 — Logic & Data Structures

181 problems

The thinking level. Students move from "can I write code?" to "can I solve problems efficiently?" Data structures, recursion, and optimization — the bridge between classroom coding and real interview challenges.

Recursion Linked Lists Stacks & Queues Trees Hashing Dynamic Programming Two Pointers

EXPERTLevel 3 — Advanced Problem Solving

163 problems

Product-company interview difficulty. Graph algorithms, tries, advanced DP, complex data structures, and optimization problems. For students targeting Google, Amazon, Microsoft, Flipkart, and similar companies.

Graphs Advanced DP Tries Segment Trees Greedy Backtracking Bit Manipulation

COMPANY-SPECIFICLevel 4 — Placement Interview Problems

165 problems

Real coding challenges modeled on questions asked by TCS, Infosys, Wipro, Cognizant, Accenture, and other campus recruiters. Timed practice that simulates actual placement coding rounds — difficulty, format, and constraints included.

How It Works

Read. Solve. Run. Validate. Repeat.

Every problem follows the same workflow — exactly like a real placement coding test. No fill-in-the-blanks. No multiple choice. Just you, a problem statement, and an empty editor.

01

Read the Problem

Each problem has a clear statement with input format, output format, constraints, and sample test cases. You understand what to solve before you write a single line.

02

Write Your Solution

Choose C, C++, Java, or Python. Write your complete solution in a full-featured code editor with syntax highlighting. No templates, no scaffolding — you write the entire program from scratch.

03

Compile & Run

Hit "Run" as many times as you need — unlimited compilations. Create your own custom test cases to check edge scenarios. Debug, iterate, and refine until your logic is right.

04

Submit & Validate

When you're confident, submit. Your code runs against automated test cases — including hidden edge cases you can't see. Pass all of them to complete the problem. Stuck? The AI assistant guides you.

How It Works

20+ Topic Categories Across All Four Levels

Problems aren't just organized by difficulty — they're also tagged by topic. Students can practice by level, by topic, or both. Here's what the question bank covers:

Loops & Iteration

for, while, nested loops, patterns

Arrays

1D, 2D, rotation, subarray problems

Strings

Manipulation, palindromes, anagrams

Number Theory

Primes, GCD, modular arithmetic

Sorting & Search

Bubble, merge, quick, binary search

Recursion

Base cases, tree recursion, memoization

Linked Lists

Singly, doubly, cycle detection, reversal

Stacks & Queues

Balancing, next greater, BFS applications

Trees

BST, traversals, height, LCA

Graphs

BFS, DFS, shortest path, cycle detection

Hashing

Frequency maps, two-sum patterns

Dynamic Programming

Knapsack, LCS, LIS, grid paths

Greedy

Activity selection, interval scheduling

Bit Manipulation

XOR tricks, power of 2, counting bits

Backtracking

N-Queens, permutations, subsets

Two Pointers

Sorted arrays, container problems

Sliding Window

Max sum subarray, substring problems

Company Patterns

TCS, Infosys, Wipro, product co. style

Performance Analytics

Every Problem You Solve Tells a Story

The platform doesn't just check if your code is right — it tracks HOW you're improving. Students see their growth. Faculty see class-level trends. TPOs see placement readiness.

Progress Tracking

Problems solved vs. total available, broken down by level and topic. See exactly where you stand.

Accuracy Rate

What percentage of your submissions pass on the first attempt? Tracks improvement over time.

Time Benchmarking

How long you take vs. the benchmark — broken down by easy, medium, and hard problems. Speed matters in placement tests.

Attempts per Problem

Fewer attempts = stronger logic. Track your average attempts and watch it drop as you improve.

Milestones & Badges

Earn progression badges as you clear level thresholds — visible on your practice profile.

Platform Features

A Compiler Built for Practice, Not Just Execution

Full-Featured Editor

Syntax highlighting, auto-indentation, and line numbers. Choose your language from a dropdown — your preference is remembered across sessions.

Unlimited Compilations

Run your code as many times as you want. No daily limits, no credit system. Practice means iteration — we don't penalize it.

Custom Test Cases

Create your own inputs to test edge scenarios before submitting. Stress-test your solution the way interviewers would.

AI Concept Assistance

Stuck? The AI guides your thinking — explaining the concept, not writing the code. Socratic hints that build understanding, not dependency.
