What is complexity analysis in algorithms?

Complexity analysis in algorithms is the study of the resources required by an algorithm to solve a problem, typically in terms of time and space.

Why is it important to analyze the complexity of algorithms?

Analyzing complexity helps in understanding the efficiency of an algorithm, allowing developers to choose the best one for their needs.

Can you explain time complexity and space complexity?

Time complexity measures the time an algorithm takes to complete as a function of the input size, while space complexity measures the memory used.

What are some common time complexity classes?

Common time complexity classes include O(1) for constant time, O(log n) for logarithmic time, O(n) for linear time, and O(n^2) for quadratic time.

How do I calculate the time complexity of an algorithm?

To calculate time complexity, analyze the algorithm's loops and recursive calls, and express the total number of operations as a function of the input size.
