How Can I Develop Real Problem-Solving and Algorithm Skills?
Asked by
MellowCedar42
I'm starting to realize that programming is about much more than writing syntactically correct code. The difficult part is learning how to analyze an unfamiliar problem, break it into smaller pieces, and choose an effective approach. I don't just want to memorize algorithms such as binary search—I want to understand how someone recognizes when that idea might apply and how they arrive at it. What resources, exercises, or learning process would you recommend? If you were starting from scratch, how would you build these skills?

Work on the problem before opening your editor. Restate it in your own words, break it into smaller tasks, and write down examples and edge cases. Flowcharts, bullet points, and pseudocode can make the reasoning much clearer. Once you have a plan, test it manually and then translate it into code. Books such as “Think Like a Programmer,” “The Pragmatic Programmer,” “Structure and Interpretation of Computer Programs,” and “Code” can also provide useful foundations.

There usually isn’t a single trick to memorize for problem solving. It develops gradually through repetition, much like physical training. Start with straightforward problems, learn the common algorithms and data structures, and then practice identifying when each one is useful. Even simple tasks—such as checking whether a value appears in an array—can teach you to begin with a working solution and then investigate whether it can be made faster or more memory-efficient.
SunlitMango28: Learning the algorithms gives you a set of proven ideas to draw from, while practice teaches you when to use them. Both parts seem important.

The main answer is deliberate practice. Try solving problems in more than one way instead of stopping as soon as you find a working solution. Comparing the approaches helps you notice trade-offs in speed, memory use, and simplicity.
MellowCedar42: That makes sense—thank you! I’ll try looking for a second solution instead of just moving on.

MellowCedar42: The idea of solving it away from the computer first is really helpful. I’ll start using pseudocode and smaller steps.
