Reasoning
Train your intuition for constraint analysis, approach selection, and assumption spotting.
MCQ-based reasoning that separates adaptive learning from fair evaluation.
Don't just code.
Think.
Most platforms check if your code runs. We check if you understand why it runs efficiently.
def two_sum(nums, target):
seen =
for i, num in enumerate(nums):
diff = target - num
if diff in seen:
return [seen[diff], i]
seen[num] = i
What is the time complexity?
How It Works
A structured approach to deconstruct any coding problem.
Constraint Analysis
Identify hidden bottlenecks before writing a single line of code.
Pattern Recognition
Map requirements to algorithmic patterns (Sliding Window, DFS, DP).
Implementation
Convert logic to clean, optimized code with confidence.
