Depth First Search must be done without recursion. (with iterative)

Ostruct Node {
};
char value; // VALUE OF NODE
list<Node*> children; // list of childrens
};
explicit Node (char value) : value(value) {}
struct Tree {
Node * root; // root of tree
explicit Tree (Node *root = nullptr) : root(root) {}
Transcribed Image Text:Ostruct Node { }; char value; // VALUE OF NODE list<Node*> children; // list of childrens }; explicit Node (char value) : value(value) {} struct Tree { Node * root; // root of tree explicit Tree (Node *root = nullptr) : root(root) {}
list<char> depthFirstSearchUpperCases (const Tree *tree) {
// TODO
return list<char>();
}
Transcribed Image Text:list<char> depthFirstSearchUpperCases (const Tree *tree) { // TODO return list<char>(); }
