Write two pseudocodes for DFS and BFS. In case you want to write real codes, try with "Stacks" for DFS and "Queues" for BFS. Examples of both are shown below. For DFS: Set found to false For BFS: Set found to false stack.Push(startVertex) DO stack.Pop(vertex) IF vertex == endVertex Set found to true ELSE Push all adjacent vertices onto stack queue.Enqueue(startVertex) DO queue.Dequeue(vertex) IF vertex == endVertex Set found to true ELSE Enqueue all adjacent vertices onto queue WHILE !queue.IsEmpty() AND !found WHILE Istack.IsEmpty() AND !found IF(lfound) Write "Path does not exist" IF(!found) Write "Path does not exist"

Transcribed Image Text:Write two pseudocodes for DFS and BFS. In case you want to write real codes, try
with "Stacks" for DFS and "Queues" for BFS. Examples of both are shown below.
For DFS: Set found to false
For BFS: Set found to false
stack.Push(startVertex)
DO
queue.Enqueue(startVertex)
DO
stack.Pop(vertex)
IF vertex == endVertex
Set found to true
queue.Dequeue(vertex)
IF vertex == endVertex
Set found to true
ELSE
ELSE
Push all adjacent vertices onto
stack
Enqueue all adjacent vertices onto
queue
WHILE !stack.IsEmpty() AND !found
WHILE !queue.IsEmpty() AND !found
IF(!found)
Write "Path does not exist"
IF(!found)
Write "Path does not exist"
