Calculating the complexity
There are two types of complexity we measure in algorithmic analysis:
- Time complexity: Time complexity is measured by the number of key operations in the algorithm. In other words, time complexity quantifies the amount of time taken by an algorithm from start to finish.
- Space complexity: Space complexity defines the amount of space (in memory) required by the algorithm in its life cycle. It depends on the choice of data structures and platforms.
Now let us focus on our implemented algorithm and find about the operations we are doing for the algorithm. In our placeAllBooks function, we are searching for each of our ordered books. So if we have 10 books, we are doing the search 10 times. If the number is 1000, we ...
