What is algorithm analysis in C++?

Algorithm analysis in C++ involves evaluating the efficiency and performance of algorithms, focusing on time and space complexity.

Why is it important to analyze algorithms?

Analyzing algorithms helps in understanding their efficiency, which is crucial for optimizing performance and resource usage in applications.

Can you explain time complexity with an example?

Sure! Time complexity measures how the runtime of an algorithm increases with the size of the input. For example, a linear search has a time complexity of O(n), where n is the number of elements.

What are some common algorithms used in C++?

Common algorithms in C++ include sorting algorithms like quicksort and mergesort, searching algorithms like binary search, and graph algorithms like Dijkstra's.

How can I analyze the space complexity of an algorithm?

To analyze space complexity, consider the amount of memory an algorithm uses relative to the input size, including both fixed and variable space.
