Study Notes

Data Sorting Algorithms

Quick Sort is a widely used sorting algorithm known for its efficiency.
Binary Search requires sorted data for optimal operation.

Quick Sort Complexity

Quick Sort has an average time complexity of O(n log n).
In the worst-case scenario, Quick Sort can degrade to O(n²), typically occurring with sorted or reverse-sorted input.

Function Definition in Python

In Python, a function is defined using the def keyword.
