📚 Quick Study Guide

  • ⏱️ In-place sorting algorithms minimize extra memory usage by modifying the input array directly.
  • 💻 Examples include Bubble Sort, Insertion Sort, Selection Sort, Heap Sort, and Quicksort (though Quicksort's space complexity can be $O(log n)$ due to recursion).
  • 🧮 Considerations: Choose in-place sorting when memory is limited and modifying the original array is acceptable.
  • ⚠️ Trade-offs: In-place algorithms may have higher time complexity compared to algorithms that use extra memory.
  • 💡 Key Benefit: Space efficiency.
