So, let us start Data Structure in Java Part 3. What are Data Structures in Java?

Graph Data Structure in Java A graph data structure in Java has the following graph data structure in java components — A set of finite vertices which are called as nodes. An edge which has a finite set of ordered pair which is in the form u, v. These kinds of graphs have much in common with each other, but significant differences are also present.

We will accentuate which kind of graphs is considered in the particular algorithm description. Edge can be drawn as a line.

Algorithm of the Week: Graphs and Their Representation

If a graph is directed, each line has an arrow. Sequence of vertices, such that there is an edge from each vertex to the next in sequence, is called path. First vertex in the path is called the start vertex; the last vertex in the path is called the end vertex. If start and end vertices are the same, path is called cycle.

Words that only differ in graph data structure in java last letter will appear consecutively in the sorted list.

4.5 Case Study: Small-World Phenomenon

Sort 4 more times, but cyclically shift the letters one position to the right so that words that differ in the ith letter will appear consecutively in one of the sorted lists.

Try out this approach using a larger word list graph data structure in java words of different sizes. Two words of different lengths are neighbors if the smaller word is the same as the bigger word, minus the last letter, e.


Extend the rules of checkers to an N-by-N checkerboard. Show how to determine whether a checker can become in king in the current move.

Show how to determine whether black has a winning move. Find an Euler path. Determining the truth value graph data structure in java a combinational circuit given its inputs is a graph reachability problem on a directed acyclic graph.

The game of Hex is played on a trapezoidal grid of hexagons Describe how to detect whether white or black has one the game using breadth first search.

Prove that the game cannot end in a tie. Prove that the first player in Hex can always win if they play optimally. This is called strategy stealing. Write a program MovieStats. Automatic memory management in languages like Java is a challenging problem.

Data Structures in Java – Graph, Trie, Segment Tree & Suffix Tree

Allocating memory is easy, but discovering when a program is finished with memory and reclaiming it is more difficult. Adjacency Matrix In the first case we store a matrix two-dimensional array with size NxN, where N is the number of vertices.

In case of directed graph, we can use 1 for the edge i,j and -1 for j,i in case the edge is directed from i to j. For a weighted directed graph we can put the weights instead of 1s.

Case Study: Small-World Phenomenon

Adjacency Lists Another useful representation of graphs are the graph data structure in java lists. In this case for each vertex we store a linked lists consisting of all of his successors. Although these two ways are the mostly used, there are also some other type of representations.

Complexity Most of the basic operations in a graph are:
