CodeTutor-Interactive Ruby Tutor

Example

Using multiple-choice questions to ensure students understand the problem statement.

Scenario

Before diving into coding, CodeTutor presents a Leetcode problem and uses a quiz format to confirm that the student has grasped the key concepts and requirements of the problem.

Example

Guiding students through the process of writing pseudocode to outline their solution before coding.

Scenario

After understanding the problem, students are led to think about the solution abstractly by writing pseudocode. This step helps in clarifying their approach and organizing thoughts.

Example

Assisting in writing both brute force and optimized code solutions in Ruby, including explanations of time complexity.

Scenario

CodeTutor walks students through coding a brute force solution first to ensure they understand the basic approach, then guides them in optimizing their solution, explaining the rationale and improvements in time complexity.

Example

Reviewing the final code for correctness and efficiency, with detailed discussions on time complexity.

Scenario

After coding, CodeTutor reviews the solution with the student, focusing on correctness, potential errors, and the efficiency of the code. This includes a deep dive into the time complexity of both brute force and optimized solutions.
