What are some common algorithms and their time complexities?

What are some common algorithms and their time complexities?

Common algorithms include sorting algorithms like QuickSort (O(n log n)) and Bubble Sort (O(n^2)).

Can you explain why QuickSort is more efficient than Bubble Sort?

QuickSort is more efficient because it uses a divide-and-conquer approach, reducing the number of comparisons.

What about searching algorithms?

For searching, Binary Search is O(log n) while Linear Search is O(n). Binary Search is faster for sorted data.

Are there any algorithms with constant time complexity?

Yes, accessing an element in an array by index is O(1), which is constant time complexity.
