What are some examples of time complexity in C++?

Time complexity in C++ refers to the computational complexity that describes the amount of time it takes to run an algorithm. Common examples include O(1) for constant time, O(n) for linear time, and O(n^2) for quadratic time.

Can you give me a specific example of O(n) time complexity?

Sure! A common example of O(n) time complexity is a linear search in an array. In this case, you check each element one by one until you find the target value.

What about O(n^2)? Any examples?

Yes! A classic example of O(n^2) time complexity is the bubble sort algorithm, where you compare each element with every other element in the array.

How does O(log n) time complexity work?

O(log n) time complexity is often seen in algorithms that divide the problem size in each step, like binary search, where the search space is halved with each iteration.
