Simple Graph Traversal with DFS, BFS, Djikstra algo.

Simple Graph Traversal

This project implements DFS, BFS, Djikstra algo.

Geting Started

Prerequites

Things you need to install this software

CMake

Installing on Unix Terminal

A step by step series of commands to get a development env running

git clone https://github.com/theorist17/graph
cd graph
mkdir build
cd build
cmake ..
make

Installing on Microsoft Visual Studio

For MSVC, built-target and input text file has to manually located.

1. Open VS
2. File -> Clone or check out code ..
3. Set Repository location = https://github.com/theorist17/graph (you need to setup github on VS first)
4. After building, move input.txt and input2.txt into the /out/build/ directory

Running the tests

Setup input.txt

3       (# of vertices)
1 2 3   (for each vertex, enumerate its adjacent vertex)
2 1 3
3 1 2
2       (# of vertices, for another graph)
1 2
2 1
4       (another graph)
1 2 3
2 4
3 2
4       (4\n)
        (eof)
