WebOct 31, 2012 · Now, with the Recursive DFS, the predecessor graph that one would obtain with source A, would be either A->B->C OR A->C->B ( A->B implies A is the parent of B in depth first tree). However, if you use the stack version of DFS, parents of both B and C, would always be recorded as A. It can never be the case that parent of B is C or vice … WebDepth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures.
