Q1. Check if graph is bipartite
Ans. 
A graph is bipartite if its vertices can be divided into two disjoint sets such that every edge connects a vertex from one set to another.
• Use depth-first search or breadth-first search to traverse the graph.

• Assign colors to the vertices alternatively as you traverse the graph.

• If at any point, an edge connects two vertices of the same color, the graph is not bipartite.
