Secondary Informatics Practice
(C++/Python)
Break algorithm problems into workable code blocks. Practise choosing, ordering, and debugging until the real solving process becomes natural.
vector<int> dp(n + 1);
dp[i] = dp[i - 1] + dp[i - 2];
cout << dp[n] << '\n';
Do not just read solutions. Practise the solving process.
Three core steps help students think about algorithms with structure.
Understand the story
Original statements introduce variables and rules through a concrete setting, then lead into the model.
Build the algorithm
Choose key steps from mixed blocks and arrange input, processing, and output into a rigorous solution.
Review mistakes
After submission, feedback points to missing steps, distractors, or ordering errors so students can revise with purpose.
