Candidate's Approach
  • The first solution was a brute force approach: traverse in order, store elements in a list, and re-construct a binary tree.
  • The interviewer suggested making in-place changes instead of reconstructing the tree.
  • The candidate was able to write the correct code for the in-place changes but felt that communication issues and needing hints may have affected their performance.
