Strengths:

• The student demonstrates a good understanding of backtracking and DFS.
• The code is clean, modular, and well-commented.
• The time and space complexity analyses are mostly accurate.

Areas for Improvement:

• For N-Queens, the space complexity analysis should include the O(n^2) space for the board in addition to the O(n) recursive stack space.
• In the Word Search solution, the found flag could be checked before proceeding with further DFS calls to avoid unnecessary computations once the word is found. For example, adding if (found) return; at the start of the dfs method could save some time.
• The comments in the code are helpful, but some additional comments explaining the overall approach or the purpose of certain blocks (like the isValid method) could make the code even more understandable.
