1, result fill in the blank: first, judge whether you can solve it quickly with the help of calendar, calculator, WPS, txt text, notepad or mathematical methods, and finally choose to crack it violently with Eclipse code.
2. Code fill-in-the-blank question: First, fill in the blanks with multiple sets of data samples to test what the output results are, especially the results returned by the method.
If the test results of multiple sets of data are correct, the time for reading and solving problems will be greatly reduced.
3, after all, the previous programming finale is more inclined to confuse miracles.
4. Before typing the code, go through all the questions and scores roughly, choose simple or high-scoring but confident writing first, and then choose other questions.
5. For difficult topics, you can write pseudo-code first, and it is often more efficient to figure out the idea before coding.
6. Although the time of the Blue Bridge Cup exam is not short, it has a large number of questions. Therefore, it is very important to allocate time reasonably.
7. The score of the blue bridge cup answer depends on the passing rate of the test data, and all the ones that can pass must be coded.
First, the main points of knowledge
Exhaustion, enumeration, dynamic programming, backtracking, graph theory, depth-first search (DFS), breadth-first search (BFS) binary tree, recursion, divide-and-conquer method, matrix method, permutation and combination, prime number, prime number, daffodil number, Euclid theorem gcd, etc.
