What it shows

  • Uses a LIFO stack or recursive call frames to explore leaf nodes first.
  • Backtracks automatically when dead ends or visited nodes are reached.
  • Ideal for topological sorting, cycle detection, and maze solving.

The takeaway

DFS plunges deep into graph branches before backtracking, using minimal memory on deep, narrow trees.
