Answer:
Wi-Fi(Wireless fidelity) is the networking technology that helps in providing the internet connectivity to the users. The Wi-Fi is all around the surrounding due to several Wi-Fi connections the users demand and use. It creates the networking environment where internet access becomes easy.
There are drawback to Wi-Fi service range that covers a large area is the high number of users.The addition of many users slow down the data rate and accessing .The radiation from this service is also a negative side of the Wi-Fi pervasiveness.
Answer:
- custom_encoded = ""
- custom_message = "this is a pen"
- custom_encoding = {
- "a": "1",
- "e": "2",
- "i": "3",
- "o": "4",
- "u": "5"
- }
-
- for c in custom_message:
- if(c in custom_encoding):
- custom_encoded = custom_encoded + custom_encoding[c]
- else:
- custom_encoded = custom_encoded + c
-
- print(custom_encoded)
Explanation:
The solution code is written in Python 3.
Let's define a variable custom_encoded with an empty string (Line 1).
Create another variable custom_message and set a sample string to it (Line 2).
Create one more variable custom_encoding to hold the mapping values between vowel and their respective encoded character (Line 3-9).
Create a for loop to loop through all the character in custom_message (Line 11) and in the loop check if the current character is found in custom_encoding dictionary, if so, use the current character to loop up the dictionary for the encoded value and add the encoded string to custom_encoded (Line 12-13). Otherwise, just add the current character to custom_encoded (Line 14-15).
At the end, print the custom_encoded to terminal and you shall get th3s 3s 1 p2n

Explanation:
We can utilize the above algorithm with a little in modification. If in each of the iteration, we discover a node with no inward edges, then we we’re expected succeed in creating a topological ordering.
If in a number of iteration, it becomes apparent that each of the node has a minimum of one inward edge, then there must be a presence of cycle in the graph.
So our algorithm in finding the cycle is this: continually follow an edge into the node we’re presently at (which is by choosing the first one on the adjacency list of inward edges to decrease the running time).
Since the entire node has an inward edge, we can do this continually or constantly until we revisit a node v for the first time.
The set of nodes that we will come across among these two successive visits is a cycle (which is traversed in the reverse direction).
