Depth-First Search (DFS) is an algorithm used to traverse or locate a target node in a graph or tree data structure. It priorities depth and searches along one branch, as far as it can go - until the end of that branch. Once there, it backtracks to the first possible divergence from that branch, and searches until ... WebOct 18, 2024 · DFS using stack. Note that I intentionally put the left neighbors later in the stack.
