Key Takeaways

You’ve mastered:

Insertion Sort Algorithm: Pick, compare, shift, insert
Implementation: Nested loops with shifting
Complexity: O(n) best, O(n²) worst/average, O(1) space
Characteristics: Stable, adaptive, in-place
When to Use: Small datasets, nearly sorted arrays

What You Can Build Now

With insertion sort knowledge, you can:

  • Sort small datasets efficiently
  • Understand adaptive sorting algorithms
  • Implement stable sorting
  • Build hybrid sorting algorithms
  • Optimize for nearly sorted data

Next Steps

  • Practice with more sorting problems
  • Learn faster algorithms (quicksort, mergesort)
  • Study hybrid algorithms (Timsort)
  • Explore optimization techniques
