Question

Please use the alphabet shown in the screenshot below to code a Depth-first search (DFS) algorithm in C++.

Depth-first search Algorithm
• Push the root node on a stack;
while (stack is not empty) {
remove (pop) the top node from the stack;
if (node is a goal node) return success;
Push all children of node onto the stack;
}
return failure;

Depth-first search
• A depth-first search (DFS) explores a
path all the way to a leaf before
backtracking and exploring another
path

C
For example, after searching A, then
B, then D, the search backtracks
and tries another path from B
