Algorithms + data structures=programs Niklaus Wirth

But, I just seem to be not able to. The point about them is scalability of programs, i.e. That's much more important than the constant factor speedup you get from switching to a lower-level programming language.

Constant O(1) - A program whose running time's order of growth is constant, executes a fixed number of operations to finish the job, thus its running time does not depend on N. And by looking at data structures in this way, it makes it immediately relevant compared to attempting to learn algorithms from a book only to not need to apply what you've learned. Linear O(N) - Program that spends a constant amount of time processing each piece of input data and thus running time is proportional to the N. It is of course, implied that the programs were written in Pascal — the technology that is used to realize the programs. Graceful performance degradation as inputs grow. Knowing how to implement and when to use which algorithms and data structures is an important skill in any language, and most algorithms can be implemented in all the mainstream languages. I know, I should just put my head down, be deterministic and write algorithms/programs on paper and implement it in practice. Niklaus Wirth famously titled his seminal book on Pascal as “Algorithms + Data Structures = Programs“. I run into the mentality of "I don't need this learning algorithms because it makes it all the more relevant to everyday coding.
