Attention: of course, these elements belong to the same level, that is, their peers. The same type of selector: last-child and: last-of-type,: nth-child (n) and: nth-of-type (n) can also be understood in this way.

The number of attacks equals to the total number of attacks minus the number of successful defenses
This question is mainly used to calculate the number of successful defenses.
Add an auxiliary array pos [] to record the number of attacks at a certain point after the last query (the first attack can be defended)
Every defensive hold once, the t0-1 attack, continue to judge the next t0 attack has included (that is, the attack to) Ask the point

To declare an inline function, we must use the "inline" keyword in the function declaration.Now we are at a point where we guess exactly what inline assembly is. It is just an assembly program written as an inline function. They are convenient, fast, and extremely useful in system programming. We mainly focus on the basic formats and usage of (GCC) inline assembler functions. To declare inline assembler fun
