A rooted binary tree is a tree with a root node in which every node has at most two children.A full binary tree (sometimes proper binary tree or 2-tree or strictly binary tree…) is a tree in which every node other than the leaves has two children. Sometimes a full tree is ambiguously defined as a perfect tree.A perfect binary tree is a full binary tree in which all leaves are at the same depth or same level, and in which every parent has two children.[1] (This is ambiguously also called a complete binary tree.)A complete binary tree is a binary tree in which every level, except possibly the last, is completely filled, and all nodes are as far left as possible.[2]An infinite complete binary tree is a tree with a countably infinite number of levels, in which every node has two children, so that there are 2d nodes at level d. The set of all nodes is countably infinite, but the set of all infinite paths from the root is uncountable: it has the cardinality of the continuum. These paths corresponding by an order preserving bijection to the points of the Cantor set, or (through the example of the Stern-Brocot tree) to the set of positive irrational numbers.A balanced binary tree is commonly defined as a binary tree in which the depth of the two subtrees of every node never differ by more than 1,[3] although in general it is a binary tree where no leaf is much farther away from the root than any other leaf. (Different balancing schemes allow different definitions of "much farther"[4]). Binary trees that are balanced according to this definition have a predictable depth (how many nodes are traversed from the root to a leaf, root counting as node 0 and subsequent as 1, 2, ..., depth). This depth is equal to the integer part of where is the number of nodes on the balanced tree. Example 1: balanced tree with 1 node, (depth = 0). Example 2: balanced tree with 3 nodes, (depth=1). Example 3: balanced tree with 5 nodes, (depth of tree is 2 nodes).A rooted complete binary tree can be identified with a free magma.A degenerate tree is a tree where for each parent node, there is only one associated child node. This means that in a performance measurement, the tree will behave like a linked list data structure. Note that this terminology often varies in the literature, especially with respect to the meaning of "complete" and "full".

# Application of binary tree in data structure?

A binary tree can be used as a simple decision tree with two options. In this case, each leaf will be a final decision arrived by traversing one branch of the tree. Anothe…r use of a binary tree is to sort numerical data in a very simple yet effective way.

# What is a balanced tree in data structures?

A balanced tree is a tree which is balanced - it has roughly the same height on each of its sub-nodes. A balanced tree will have the lowest possible overall height. Fo…r example, a balanced binary search tree will have equal heights (plus or minus one) on the left and right sub-trees of each node. This ensures that operations on the tree always are guaranteed to have O(lg n) time, rather than the O(n) time that they might have in an unbalanced tree. Certain tree algorithms are designed for ensuring that the tree stays balanced at all times, while maintaining the O(lg n) time for all operations. Such algorithms, such as red-black trees, AVL trees, and others, are generally used in standard library implementation of binary search trees.

# What kind of data type is a structure?

A structure is not a data type. A structure is more of a collection if data types that can be referenced conveniently. Mainly we humans can keep on top of it, the computer doe…s not care. struct foo { int a; long b; float c; char d[512]; int *e; };

# What is avl tree in data structure?

Avl tree is self binary tree in which balancing factor lie between the -1 to 1.It is also known as self balancing tree. so BF=h(T(left sub tree))-h(T(right sub tree));

# What is spanning tree in data structure?

spanning tree is a tree which is used to find optimum path of a given graph

# What is nonlinear data structure and his graph and tree?

see array is linear on it requires continues memory locations. the data structures like linked list does not require such continues memory locations.which requires the size sp…ecified should be there in memory. thank you for reading my answer anu mohan aamh04

# What are the advantages of trees in data structures?

The tree structure is useful because it easily accommodates the creation and deletion of folders and files.

find the minimum cost of the path to reach the desired node

# What are the different types of data structure?

basically there are two types of data structure, 1) linear : array, stack, queue 2)non linear : linked list, tree...

# What are the applications of trees in data structures?

Using binary tree, one can create expression trees. The leaves of the expression tree are operands such as constants, variable names and the other node contains the operator (…binary operator). this particular tree seems to be binary because all the operators used are binary operators. it is also possible for a node to have one node also, in case when a unary minus operator is used. we can evaluate an expression tree by applying the operator at the root to the values obtained by recursively evaluating the left and right sub trees.
