WebSep 6, 2016 · You can convert a tree structure into a graph structure by fully traversing the tree in any manner, but the efficiency depends on the actual data structures involved. – … In graph theory, a tree is an undirected graph in which any two vertices are connected by exactly one path, or equivalently a connected acyclic undirected graph. A forest is an undirected graph in which any two vertices are connected by at most one path, or equivalently an acyclic undirected graph, or equivalently a disjoint union of trees.

We can partition the vertices of T' into two groups, A and B. A will contain all vertices from even numbered rows of T', and B will contain all vertices from odd numbered rows from T'. Thus, we've created a bipartition of T', so T is a bipartite graph.
