Strengths:

• Both solutions correctly implement the required algorithms and solve the problems efficiently.
• The code is readable and well-structured, with good variable naming.
• The logic is clear and follows best practices for BFS and topological sorting.

Areas for Improvement:

• In problem1.cs, the indentation inside the if blocks for node.left and node.right could be improved for better readability.
• The variable count in problem1.cs is not necessary since the loop condition already ensures the correct number of iterations. The loop could be simplified to use size directly.
• In problem2.cs, the adjacency list could be initialized more efficiently by pre-allocating space if the number of prerequisites is known, though this is a minor optimization.
