Solution

To determine if a given data set represents a valid UTF-8 encoding, we can write a method called validUTF8. This method will take in the data set as a list of integers.

The first step is to iterate through each integer in the data set. For each integer, we need to check if it represents a valid UTF-8 character.

A UTF-8 character can be 1 to 4 bytes long, so we need to examine the 8 least significant bits of each integer. To do this, we can use bitwise operations.

Next, we need to check if the integer represents a single-byte character. In this case, the most significant bit of the integer should be 0. If it is not, then the data set is not a valid UTF-8 encoding and we can return False.

If the most significant bit is 0, we can move on to checking for multi-byte characters. In this case, we need to count the number of consecutive 1s starting from the second most significant bit. This will tell us how many bytes the character should have.

If the count is 1 or greater than 4, then the data set is not a valid UTF-8 encoding and we can return False.

If the count is between 2 and 4, we need to check that the next bytes in the data set start with the binary pattern "10". If any of the following bytes do not start with "10", then the data set is not a valid UTF-8 encoding and we can return False.

If we have successfully checked all the bytes in the data set and they all meet the UTF-8 encoding requirements, then we can return True.

To test the validUTF8 method, we can create a main file and call the method with different data sets. We can print the result of each test case to verify if the method is working correctly.

The expected output for the provided test cases is True, True, False.

The code for the validUTF8 method and the main file can be found in the GitHub repository under the directory "0x04-utf8_validation" and the file "0-validate_utf8.py".

Question No. 1: (Marks 10) Suppose a Station A transmits a message containing five characters to Station B using Even Parity encoding to ensure data integrity during transmission. Each character consists of 8 bits encoded in the ASCII. Station B receives the message of five 9-bit data elements and needs to extract the 8-bit data message from each element and decode it using ASCII to form meaningful words. The data elements received by Station B are: Received 9-bit Data Elements: 010101100 010101010 010011001 010011010 010100110 Assuming the data is received correctly without any errors by Station B, you are required to do the following tasks: 1. Extract 8-bit Data Message: Remove the Parity bits to extract the 8-bit data message from each 9-bit received element. 2. Decode and Extract using ASCII: Convert each 8-bit data message into its corresponding ASCII character to extract the meaningful words. Give your answer in the following table: Received Message 010101100 010101010 010011001 010011010 010100110 Data message (Bits)? Decoded Message?
