To judge a complete binary tree:Complete binary tree, except the last layer, each layer of the node tree has reached the maximum value; On the last layer only a few nodes on the right are missing!Algorithm ideas:Traversing a binary tree by hierarchy

The following two C + + classes are available:classBase { Public: Base (intAintb): M_a (a), M_b (b) {}Virtual voidFunc1 (); Virtual intFunc2 ();Private: intm_a, M_b;}classDerived: PublicBase { Public: Derived (intAintBDoubled): Base (A, B), M_d (d)

Select Sort:It is known that a set of unordered data a[1], a[2] 、、、、 a[n], if it is sorted in ascending order.The value of a[1] and a[2] is compared first, if A[1] is greater than a[2, the value of both is exchanged, otherwise it is unchanged.Then

Originally to look at the C + + object model to assign a child object to a parent object and the parent type pointer to the field, whether or not to cut, open Codebloks wrote the following code, the compiler chose GNU.1 #defineDEBUG (X) std::cout2 3

In C + +, vector is a very useful container, and here is a summary of the container.1 Basic operations(1) header file #include.(2) Create vector object,vector VEC;(3) Insert number at tail: vec.push_back (a);(4) Use subscript to access the

In a directory to write some of the single-file C or C + + files, each time to knock out commands such as g++ a.cpp-o a feeling more troublesome.So just imitate makefile function, realize scan current directory, and all C file, cc file, CPP file

C # is a secure, stable, simple, fully object-oriented programming language derived from C and C + +. It inherits the power of C and C + + while removing some of their complex features (for example, no macros and templates, multiple inheritance is

idea: Similar to a topological sorting problem, according to the degree of 1 points, it is connected to the number of edges is different or and this rule, directly to the topological sort. Each time the resulting node is reduced by one, and xor the

The singleton means the only instance, which ensures that the instance initializes itself and provides this instance to the system as a singleton class.1, the main points of the singleton mode:One is that a class can have only one instance.The
