Breadth-first search starts at a given vertex h, which is at level 0. In the first stage, we go toall the vertices that are at the distance of one edge away. When we go there, we markedas "visited," the vertices adjacent to the start vertex s - these vertices are placed into level 1.In the second stage, we go to all the new vertices we can reach at the distance of two edgesaway from the source vertex h. These new vertices, which are adjacent to level 1 vertex and notpreviously assigned to a level, are placed into level 2. The BFS traversal ends when each vertexhas been finished.The BFS(G, a) algorithm creates a breadth-first search tree with the source vertex, s, as its root.The predecessor or parent of any other vertex in the tree is the vertex from which it was firstdeveloped. For every vertex, v, the parent of v is marked in the variable π[v]. Another variable,d[v], calculated by BFS has the number of tree edges on the way from s tov. The breadth-firstsearch needs a FIFO queue, Q, to store red vertices.Algorithm: Breadth-First Search TraversalBFS(V, E, a)1.2. do color[u] ← BLACK3. d[u] ← infinity4. π[u] ← NIL5. color[s] ← RED ?

Suppose that there is a Beta(2,2) prior distribution on the probability theta that a coin will yield a "head" when spun in a specified manner. The coin is independently spun 10 tim
Q. Reverse the order of the elements on a stack S (i) by using two additional stacks (ii) by using one additional queue. Ans : L e t S be the stac
what are registers? why we need register? Definition? Types? What registers can do for us?
Q. Write down an algorithm to merge the two sorted arrays into the third array. Do not perform the sort function in the third array. Ans: void m
what algorithms can i use for the above title in my project desing and implmentation of road transport booking system
An interesting application or implementation of trees is the playing of games such as tie-tac-toe, chess, nim, kalam, chess, go etc. We can depict the sequence of possible moves
Q. Make a BST for the given sequence of numbers. 45,32,90,34,68,72,15,24,30,66,11,50,10 Traverse the BST formed in Pre- order, Inorder and Postorder.
what is tower of management with example
AVL trees are applied into the given situations: There are few insertion & deletion operations Short search time is required Input data is sorted or nearly sorted
