Practice Smarter,
Not Harder.
SimiloxLabs is the coding-practice platform built for clarity — curated problem sets, instant AI feedback, and secure contests designed by educators for students.
Given an array of integers nums and an integer target, return indices of the two numbers that add up to target.
function twoSum(nums, target) {const map = new Map();
for (let i = 0; i < nums.length; i++) {const diff = target - nums[i];
if (map.has(diff)) {return [map.get(diff), i];
}
map.set(nums[i], i);
}
}
Everything you need to level up.
A platform designed from the ground up to make coding practice feel less like a chore and more like progress.
Problems Library
500+ problems curated by professors and the SimiloxLabs team — organized by topic, difficulty, and learning path.
AI-Powered Feedback
Get instant, actionable feedback on every submission: time complexity, space analysis, edge cases, and cleaner approaches.
Secure Contests
Run fair, integrity-first competitions with built-in anti-cheat measures, proctoring tools, and tamper-proof rankings.
From zero to solved in four steps.
Pick a Problem
Browse our professor-curated library by topic, difficulty, or learning path. Filter by tag or search for something specific.
Write & Submit
Code in 12+ languages in our browser editor. Run against public and hidden test cases, then submit when you're ready.
Get AI Feedback
Receive immediate feedback on correctness, complexity, readability, and alternative approaches — not just pass/fail.

Compete fairly. Rank honestly.
SimiloxLabs contests are built with academic integrity at the core. From the moment you open a contest, every action is monitored to ensure a level playing field for every participant.
Browser Tab Locking
Tab-switch detection flags suspicious activity in real time.
Session Monitoring
Every submission is timestamped and associated with a secure session.
Fair Ranking
Rankings computed on verified submissions only — no gaming the leaderboard.
Time
O(n log n)
Space
O(n)
Suggestions
Your divide step is correct. Consider using mid = lo + (hi - lo) // 2 to avoid integer overflow in very large arrays.
Not just pass or fail — real insight.
Every submission on SimiloxLabs is analyzed by our AI engine, giving you the kind of feedback a mentor would — not just whether it works, but how to make it better.
