What is algorithm analysis in C++?

Algorithm analysis in C++ involves evaluating the efficiency of algorithms in terms of time and space complexity.

Why is it important to analyze algorithms?

Analyzing algorithms helps in choosing the most efficient one for a given problem, which can significantly improve performance.

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, as well as search algorithms like binary search.

How can I analyze the space complexity of an algorithm?

Space complexity is analyzed by determining the amount of memory an algorithm uses relative to the input size, including both fixed and variable space.
