How can I reduce time complexity in algorithms?

To reduce time complexity, you can optimize your algorithms by using more efficient data structures, applying divide and conquer strategies, or using dynamic programming.

Can you give me an example of using dynamic programming?

Sure! A classic example is the Fibonacci sequence. Instead of using a simple recursive approach, you can store previously computed values to avoid redundant calculations.

What about using data structures?

Using appropriate data structures like hash tables can significantly reduce time complexity for search operations from O(n) to O(1).

Are there any algorithms that inherently have low time complexity?

Yes, algorithms like QuickSort and MergeSort have average time complexities of O(n log n), which are efficient for sorting large datasets.
