Graph coloring using backtracking in c

WebThe vertex coloring is a way of coloring the vertices of a graph such that no two adjacent vertices share the same color. A coloring using at most k colors is called a (proper) k–coloring, and a graph that can be assigned a (proper) k–coloring is k–colorable.
