method can be executed independently. When there are many methods for testing using junit, each method outputs content to the console, and people cannot manually check the content.* Automated result check-AssertAssertion principle: Call A method. Before calling a method, prepare test data and test data running results ---- compare the actual results with the expected results * When writing a standalone test, do not test the correct data and results, and test the incorrect data (invalid data) XM
What I was able to find at the C + + committee meeting was the smartest group of people in the C + + community who were in the crowd, answering questions for me.

During the interview, algorithm questions are necessary. Through algorithms, we can see a programmer's programming thinking, examine the design and analysis capabilities for complex problems, and reflect the rigor of the problem. Algorithms are a series of clear instructions for solving problems, that is, they can obtain the required output within a limited period of time for certain standard input. Algorit
