What are some real-world examples of algorithm efficiency?

Algorithm efficiency refers to how well an algorithm performs in terms of time and space. For example, sorting algorithms like QuickSort and MergeSort are efficient for large datasets.

Can you explain how QuickSort works?

Sure! QuickSort is a divide-and-conquer algorithm. It selects a 'pivot' element and partitions the array into two sub-arrays: elements less than the pivot and elements greater than the pivot. It then recursively sorts the sub-arrays.

What about searching algorithms?

For searching, Binary Search is a great example of efficiency. It works on sorted arrays and reduces the search space by half with each step, achieving O(log n) time complexity.

Are there any real-world applications of these algorithms?

Absolutely! QuickSort is used in various applications like database sorting, while Binary Search is used in search engines and databases to quickly find data.
