Bubble Sort
Though inefficient for large datasets, Bubble Sort's simplicity makes it a foundational pedagogical tool for understanding swaps and iterative passes.

O(n log n)O(log n)
Quicksort
A highly efficient, divide-and-conquer sorting algorithm that picks an element as 'pivot' and partitions the array around it.
Divide & Conquer
O(n log n)O(n)
Mergesort
A stable, comparison-based sorting algorithm. It divides the input array into two halves, calls itself for the halves, and then merges them.
Stable Sort
O(n log n)In-Place
Heapsort
Comparison-based sorting technique based on Binary Heap data structure. It is similar to selection sort where we find the maximum element.
Selection Based
O(n^2)O(n) Best Case
Insertion Sort
Efficient for small data sets and nearly sorted arrays. Builds the final sorted array one item at a time.
