from collections import deque

def bfs(graph, start):
    visited = set()
    queue = deque([start])

    while queue:
        vertex = queue.popleft()
        print(vertex)  # You can modify this line to process the vertex

        if vertex not in visited:
            visited.add(vertex)
            neighbors = graph[vertex]

            for neighbor in neighbors:
                if neighbor not in visited:
                    queue.append(neighbor)

# Example usage:
# Define your graph as an adjacency list
graph = {
    'A': ['B', 'C'],
    'B': ['D', 'E'],
    'C': ['F'],
    'D': [],
    'E': ['F'],
    'F': []
}

start_vertex = 'A'
bfs(graph, start_vertex)
