What it shows

  • Recursively splits array in half until individual elements remain.
  • Merges sorted halves using two pointers in O(n) auxiliary space.
  • Guarantees stable O(n log n) worst-case time complexity.

The takeaway

Predictable O(n log n) runtime makes Merge Sort the gold standard for linked lists and external storage.
