What is the trick to finding the least common multiple?
Prime factor tree!
What is the number of nodes of degree 2 in binary tree which has n leaf nodes?
Ne=N2+1Here Ne=no. of leaf nodesN2= no. of nodes of degree 2
Can you show me the factor tree of 99?
99 33,3 11,3,3
If the degree of a node is 0 then the tree is called?
This would be just a single node, since no edges (you can think of degree as the number of edges connected to a node). If you are talking about the in-degree, or out-degree of a node being zero, this can happen many times in a directed graph (in-degree = # edges going IN to node, out-degree = # edges going out...).
Can you show me a factor tree for 36?

Show that atree has at least tow vertices of degree 1?
Show that a tree has at least 2 vertices of degree 1
What is the difference between a minimum spanning tree and a shortest path in graph theory?
In graph theory, a minimum spanning tree is a tree that connects all the vertices of a graph with the minimum possible total edge weight, while a shortest path is the path with the minimum total weight between two specific vertices in a graph. In essence, a minimum spanning tree focuses on connecting all vertices with the least total weight, while a shortest path focuses on finding the path with the least weight between two specific vertices.
A tree with n vertices has edges?
A tree with n vertices has n-1 edges.
Show that the star graph is the only bipartiate graph which is a tree?
A star graph, call it S_k is a complete bipartite graph with one vertex in the center and k vertices around the leaves. To be a tree a graph on n vertices must be connected and have n-1 edges. We could also say it is connected and has no cycles. Now a star graph, say S_4 has 3 edges and 4 vertices and is clearly connected. It is a tree. This would be true for any S_k since they all have k vertices and k-1 edges. And Now think of K_1,k as a complete bipartite graph. We have one internal vertex and k vertices around the leaves. This gives us k+1 vertices and k edges total so it is a tree. So one way is clear. Now we would need to show that any bipartite graph other than S_1,k cannot be a tree. If we look at K_2,k which is a bipartite graph with 2 vertices on one side and k on the other,can this be a tree?
Prove that every tree with two or more vertices is bichromatic?
Prove that the maximum vertex connectivity one can achieve with a graph G on n. 01. Define a bipartite graph. Prove that a graph is bipartite if and only if it contains no circuit of odd lengths. Define a cut-vertex. Prove that every connected graph with three or more vertices has at least two vertices that are not cut vertices. Prove that a connected planar graph with n vertices and e edges has e - n + 2 regions. 02. 03. 04. Define Euler graph. Prove that a connected graph G is an Euler graph if and only if all vertices of G are of even degree. Prove that every tree with two or more vertices is 2-chromatic. 05. 06. 07. Draw the two Kuratowski's graphs and state the properties common to these graphs. Define a Tree and prove that there is a unique path between every pair of vertices in a tree. If B is a circuit matrix of a connected graph G with e edge arid n vertices, prove that rank of B=e-n+1. 08. 09.
Name the storage representation of a tree?
A tree stores data in nodes or vertices.
1 sketch all binary tree with six pendent vertices?
A binary tree with six pendent vertices will have five internal nodes. The pendent vertices will be attached to these internal nodes. The tree will have a root node with two child nodes, each of which will have two child nodes, resulting in a total of six pendent vertices. The structure will resemble a balanced binary tree with a depth of two.
What is Difference between tree and spanning tree?
A tree is a connected graph in which only 1 path exist between any two vertices of the graph i.e. if the graph has no cycles. A spanning tree of a connected graph G is a tree which includes all the vertices of the graph G.There can be more than one spanning tree for a connected graph G.
Draw all trees of n labeled vertices for n123?
I can provide a list of combinations of trees with 1, 2, and 3 vertices. 1 labeled vertex: Vertex A 2 labeled vertices: Tree 1: Vertex A connected to Vertex B 3 labeled vertices: Tree 1: Vertex A connected to Vertex B, Vertex C disconnected from A and B
What are the 3 parts of a triangle?
The tree main parts of a triangle are the sides, the angles and the vertices.
What is the minimum spanning tree of an undirected graph g?
The minimum spanning tree of an undirected graph g is the smallest tree that connects all the vertices in the graph without forming any cycles. It is a subgraph of the original graph that includes all the vertices and has the minimum possible total edge weight.
Why don't we allow a minimum degree of B-Tree is 1?
One important property of a B-Tree is that every node except for the root node must have at least t-1 keys where t is the minimum degree of the B tree. With t-1 keys, each internal node will have at least t children [Cormen et al., Introduction To Algorithms Third Edition, MIT Press, 2009 p. 489].If we allow a minimum degree of 1, then each internal node will have 1-1=0 keys!
