Our effecect visited China recently. I had a 1-1 with him and several meetings. Gains from effecect:1.Algorithm: It wocould be good to keep doing some practice regularly for example project Euler, but it's fine to not put effort on it on intention.

Now we are working on an addin project. It was just a simple thing. A new feature demand gave me the opportunity to get a bit of Interprocess code. Although coding is not complex, it does deepen the understanding of Interprocess sync. Note it

Note this question because you are more aware of the necessity and importance of breaking the "inertial thinking" to solve the problem. We should consider it from another angle when solving problems in the future. From coolshell The following is a

According to the valid STL rule, the STL algorithm is more effective than self-writing loop traversal in terms of efficiency and correctness. I have never paid attention to this before. From now on, pay attention to it. Learn the following three 1.
