What Is Referred To As The Recursive Case? General case (Recursive case): the case in a recursive definition in which the method is calling itself. Indirectly recursive: a method that calls another method and eventually results in the original method call. Recursive definition: a definition in which an entity is defined in terms of a
Why Is Recursion Used In Programming? Recursion is made for solving problems that can be broken down into smaller, repetitive problems. It is especially good for working on things that have many possible branches and are too complex for an iterative approach. … Trees and graphs are another time when recursion is the best and
Can Undirected Graphs Have Cycles? An undirected graph is acyclic (i.e., a forest) if a DFS yields no back edges. Since back edges are those edges ( u , v ) connecting a vertex u to an ancestor v in a depth-first tree, so no back edges means there are only tree edges, so there
