Methods can be associated with a named type or a pointer to a named type. We just saw two Abs methods. One on the *Vertex pointer type and the other on the MyFloat value type. There are two reasons to use a pointer receiver. First, to avoid copying t…
Go does not have classes. However, you can define methods on struct types. The method receiver appears in its own argument list between the func keyword and the method name. package main import ( "fmt" "math" ) type Vertex struct { X,…
In fact, you can define a method on any type you define in your package, not just structs. You cannot define a method on a type from another package, or on a basic type. package main import ( "fmt" "math" ) type MyFloat float64 func (f…

Euler Tour Tree最大的优点就是可以方便的维护子树信息,这点LCT是做不到的.为什么要维护子树信息呢..?我们可以用来做fully dynamic connectivity(online). Euler Tour Tree 维护将树中的边u--v变成u->v,v->u后的Euler Tour. 换根: 因为Euler Tour是一个环,那么我们可以在任意一个k->u的地方切断,然后把这段东西接到最后去,这样就把u变成根了 Link: 先换根,然后添加u->v与v->…
