<div class="textblock"><p>Algorithm to check whether a graph is <a href="https://en.wikipedia.org/wiki/Bipartite_graph" target="_blank">bipartite</a> </p>
<p>A graph is a collection of nodes also called vertices and these vertices are connected by edges. A graph is bipartite if its vertices can be divided into two disjoint and independent sets U and V such that every edge connects a vertex in U to one in V.</p>
<p>The algorithm implemented in this file determines whether the given graph is bipartite or not.</p>

Example - Here is a graph g1 with 5 vertices and is bipartite

/ \ / \
2 3 5
Example - Here is a graph G2 with 3 vertices and is not bipartite
