.. NET in the timerQ:. NET provides a few timer typesSystem.Windows.Forms.Timer, System.Threading.Timer, System.Timers.Timer. System.Windows.Forms.Timer is characterized by inaccurate timing and missed beats; System.Threading.Timer is recommended.Add: System.Threading.Timer and System.Timers.Timer have the possibility of a method re-entry problem, System.Windows.Forms.Timer does not exist this problem. In fact, the System.Windows.Forms.Timer type does not involve multi-threaded operations, the s

types.Q: What are the primary and secondary constraints of genericsEach generic parameter can have at most one primary constraint, and the primary constraint for generics is that the specified generic parameter must be or inherit from a reference type, with two special primary constraints: class and struct, representing the generic parameter as a reference type and a value type, respectively. Each generic parameter can have an infinite number of minor constraints, and the syntax for the seconda

Ideas:The DFS sequence is actually something very water. Like the tree chain, it's a hash of the tree chain.The problem is: Each subtree is assigned a value of 1, a point assignment of 0, the minimum value of the query subtree.The question needs to be noted: When we assign a value of 1 to a subtrees tree, we have to query the value of the subtree before the minimum value is 0, if so, to make the subtree parent node becomes 0, or 0 of the information will be lost.See the code for details:#include
