Certification came!
School recently organized a new round of CSP / CCF certification, algorithms are not familiar with nothing at the end, ready to practice starting today basis.
Before authentication, what do I know?
Talk about certification preparation before it, first on the tangle sign language, and had thought can only be written in C, the result can now have a C / C ++, Java, Python. Registration Pyhton would have wanted to be the result of Python's IDLE nausea live, even with a number of debugging features is immune, when they could spend vscode ah!
On the C C ++ and Java options /, chose Java. Not for C / C ++ are not familiar with, but the standard C's in there too messy, difficult to ensure the right on your computer code to the server what will be look, so chose Java.
The same piece of code to run very different, choose carefully!
I tested the same code on the official website of the environment, time-consuming and memory accounted for as follows
- Time: C / C ++ <Python <Java
- Memory: C / C ++ <Python <Java
Java does not feel much advantage.
Item difficulty
Looked simulation questions, difficult questions feel the ladder a bit poor, do not think a simple question, but rare problem needs to be carefully considered from the language.
Expect
Pictures and code, paste the URL did too, and so finished the test, carefully and we talk about feelings, give us suggestions point, 9/7 day today, there are about seven days away from the exam, hoping he can become a big God from white .
