Module 1
Emergency Sprint — OA Execution and Coding Reliability
1
Defining Problem Contracts, Invariants, and Edge Cases
Convert a problem statement into a precise input-output contract, invariants, and edge cases before coding.
Inferring Time and Space Complexity from Input Constraints
Infer the required asymptotic time and space complexity from input constraints.
3
Choosing Between C++ and Python for Problem Solving
Select C++ or Python for a problem using constant factors, numeric behavior, recursion limits, and library support.
Designing Boundary, Adversarial, and Language-Specific Tests
Construct boundary, adversarial, and language-specific tests for a proposed solution.
5
Minimal Counterexamples and Invariant Violations
Reduce a failing implementation to a minimal counterexample and identify the violated invariant.
6
Time Management Strategies for OA Problems
Apply a fixed time budget for reading, attempting, parking, and revisiting OA problems.
