Binary Tree


Given a Binary Tree, convert it into its mirror.
What is a Binary Tree?

 ➤A binary tree is made of nodes, where each node contains a "left" reference, a "right" reference, and a data element. The topmost node in the tree is called theroot. Every node (excluding a root) in a tree is connected by a directed edge from exactly one other node. This node is called a parent.
            

Input:
➤The task is to complete the method that takes one argument, root of Binary Tree and modifies the tree.

Output: 
➤The function should convert the tree to its mirror.
Plus: 
Check whether the binary tree and mirror tree is same or not.

Kruskal’s Minimum Spanning Tree Algorithm & Programme

PROBLEM :                  Kruskal's algorithm is a minimum-spanning-tree algorithm which finds an edge of the least possible weight that connects any two trees in the forest. It is a greedy algorithm in graph theory as it finds a minimum spanning tree for a connected weighted graph adding increasing cost arcs at each step. To understand Kruskal's algorithm let us consider the following example − Step 1 - Remove all loops and Parallel Edges Remove all loops and parallel edges from the given graph. In case of parallel edges, keep the one which has the least cost associated and ove all others. Step 2 - Arrange all edges in their increasing order of weight The next step is to create a set of edges and weight, and arrange them in an ascending order of weightage (cost). Step 3 - Add the edge which has the least weightage Now we start adding edges to the graph beginning from the one which has the least weight. Th...

Adaptive Software Development (ASD)

Adaptive Software Development (ASD) :- Adaptive Software Development(ASD) has been proposed by Jim High smith as technique for building complex software and system. ASD focus on human collaboration and team self-organization. Jim High smith defines an ASD "Life Cycle" that consist of three phases  Speculation Collaboration learning  During speculation, the project is initiated and adaptive cycle planning is conducted. Adaptive cycle planning uses project Initiation information,the customer's mission statement ,basic requirements and project constraint to define the set of release cycles that will be required for the project. Collaboration encompasses communication and team-work but it also enphasizes individualism because individual creativity plays an important role in collaborative thinking.It is all above all,a matter of trust. people working together must trust one another to comment without war help without irritation work as hard as ...

Dijkstra's algorithm

Djikstra's algorithm   solves the problem of finding the shortest path from a point in a graph (the  source ) to a destination. It turns out that one can find the shortest paths from a given source to  all  points in a graph in the same time, hence this problem is sometimes called the  single-source shortest paths  problem. This problem is related to the spanning tree one. The graph representing all the paths from one vertex to all the others must be a spanning tree - it must include all vertices. There will also be no cycles as a cycle would define more than one path from the selected vertex to at least one other vertex. For a graph, G = (V,E) where V is a set of vertices and E is a set of edges. Dijkstra's algorithm keeps two sets of vertices: S    the set of vertices whose shortest paths from the source have already been determined  and V-    S :   the remaining v...
