"feedback" : "Exercise: mergesort\n\n### 1. Correctness\n- \n\n### 2. Suggestion\n- \n\n### 3. Code Style\n- In `merge`, your variable naming (`i`, `j`, `k`) is fine, but the comments are slightly misleading: `i`/`j` are not “left half/right half” in general, but specifically pointers into the ranges `a[beg..m-1]` and `a[m..end-1]`—consider phrasing comments in terms of those index intervals to match the task description.\n- You mix two copying approaches compared to the exercise text (it describes copying `b` back “as an unchanged block”; you use `System.arraycopy`, which is totally fine). If this is for a learning exercise about loops/invariants, consider whether the course expects a manual loop here (not a correctness issue, but could be a grading expectation depending on the rules).\n",
