A Network is definitely a Tree when any of the below properties matched.

Explanation:

A Network is synonym for connected graph. Connected graph is a graph is a path which will connect from vertex to vertex.

A Tree is a network that has no circuit. network can be differed from tree by three key properties

1. Single path property - one path connecting two vertices

2. All bridges property - every edge of a network is a bridge

3. N-1 edges property - N vertices has N-1 edges

To determine this we use to N-1 edges property as given number of vertices and no bridges.

If a network has 15 vertices it must have 15-1= 14 edges to become a tree

Write an expression to print each price in stock_prices. Sample output with inputs: 34.62 76.30 85.05
Lana71 [14]

Answer:

Here is the Python program:

stock_prices = input().split() #to take input and splits it into a list

for price in stock_prices: #iterates through stock_prices

   print("$",price) #prints each value of stock_prices with a dollar sign

Explanation:

The program is well explained in the attached comments. I will explain the logic of the program with the help of an example:

Suppose the user enters the following input as stock_prices values

34.62 76.30 85.05

input() method is used to take input from user

split() method is used to split or break this input string and returns a list of strings as:

['34.62', '76.30', '85.05']    

Now the statement for price in stock_prices: iterates through each item of the list and print("$",price) prints each value of list with a dollar sign on the output screen as:

$ 34.62                                                                                                            

$ 76.30                                                                                                            

$ 85.05
