Iterative Quicksort
Iterative Quicksort Implementation: A Deep Dive
In my previous work, I explored quicksort using recursion. Today, I'm excited to share an alternative approach: iterative quicksort.
This implementation leverages the power of a stack data structure and employs Lomuto's partitioning algorithm to efficiently sort elements.
Key Concepts:
1. Stack: A stack is used to store ranges (start and end indices) representing unsorted portions of the list.
2. Pivot Index: The _pivotIndex function, based on Lomuto's algorithm, identifies the pivot element and places it in its correct position.
3. Iterative Process: The algorithm iteratively pops ranges from the stack, partitions them around the pivot, and pushes new ranges back onto the stack until the entire list is sorted.
