What you type
Create a top-down breadth-first search algorithm flowchart: read graph G and start vertex s, mark s visited and enqueue it, then while the queue is nonempty dequeue a vertex, record it in traversal order, and mark and enqueue each unvisited neighbor. Output the traversal order and end.
Then tryAdd a distance label when each neighbor is enqueued.Change the output to stop when a target vertex is found.

The drawing

What a flowchart is.

A flowchart is a diagram of a sequence. Rectangles represent steps, diamonds represent decisions, and arrows show what happens next. Start and end shapes make the boundary of the process clear.

Use a flowchart when the order of actions matters or when a choice can send work down different paths. Keep each box short enough to scan and label decision branches with the outcome that leads to them.

Describe it

One paragraph is enough to start.

“Create a top-down breadth-first search algorithm flowchart: read graph G and start vertex s, mark s visited and enqueue it, then while the queue is nonempty dequeue a vertex, record it in traversal order, and mark and enqueue each unvisited neighbor. Output the traversal order and end.”

FAQ

Common questions

What is a flowchart?

It is a diagram that uses shapes and arrows to show the order of steps and decisions in a process or algorithm.

What shapes are used in a flowchart?

A rectangle commonly represents a step, a diamond represents a decision, and rounded shapes mark the start or end.

When should I use a flowchart?

Use one to explain a process, troubleshoot a decision path, document an algorithm, or align a team on what happens next.

How do I make a flowchart clear?

Use short action labels, show the normal path first, label decision outcomes, and avoid adding steps that do not affect the flow.
