WebDepth-first search is a common way that many people naturally approach solving problems like mazes. First, we select a path in the maze (for the sake of the example, let's choose a path according to some rule we lay out ahead of time) and we follow it until we hit a dead end or reach the finishing point of the maze. WebIn addition, the depth first search will make use of two additional instance variables in the Vertex class. The new instance variables are the discovery and finish times. The … WebThe finish time is the number of steps in the algorithm before a vertex is colored black.
