Consider the hex strings A=0x09a3b4fd83b08d2c and B=0xd09d4a09cba24e45. a) What is A B in hexadecimal? Please give your answer a leading Ox and use lowercase letters only. Make sure you use exactly 16 hex digits (which may involve typing in leading zeros). hexadecimal: b) Suppose that A was generated uniformly at random from all 8 byte strings. What is the probability that the second binary digit of A is 1? c) Suppose that A was generated uniformly at random from all 8 byte strings. What is the probability that the second binary digit of A B is 1?

Description i What is timestamp? Note that we have only timestamps, which ALWAYS contain yyyy-mm-dd as a date, hh:mm:ss as a time, and +/-zzzz as a timezone. time 2017-10-14 00:11:20 +0000 date time zone 12345 + timeconverter.py 1 def convert_time(timestamp): #NOTE: COMPLETE THE CODE FROM HERE! 6 #DO NOT MODIFY THE CONTENT HERE: 7 def print_result(hour, minute): 8 9 print("The time is {}:{}".format(hour, minute)) 10 #DO NOT MODIFY THE CONTENT HERE: 11 timestamp_list = ['2017-10-14 00:11:20 +0000', 12 '2022-03-24 07:22:16 -0400' Topic: Timestamp Converter Write a program timeconverter.py that has two functions: 1) The function convert_time : for extracting the hour and minute from a timestamp and 2) The function print_result: for printing the results. Note that the two functions should be called under the loop. 1) The function convert_time should: 1. take the timestamp from the function call, 2. separate time from date and time zone, 3. split it into hour, minute and seconds, 4. extract…
Q4: Show how to generate a codeword for the dataword “10011010" if CRC is used for coding with the divisor "1101".
In Python Create a program that reads a full name as a single string, and and uses the split creates a username with the following rules: The first character of the username is the first character of the first name. The second character of the username is the first letter of the middle name, if one was provided. The rest of the characters will be a prefix of the last name, long enough to meet the length requirement. The username can have up to 8 characters only, and in lowercase.

this code only prints random dna letters where is the game there are the questions below Find the complement of a DNA strand: recall that a DNA strand is a combination of fouruppercase letters; A, T, C, and G. The letters A and T are complements, and the letters Cand G are complements. To find the complement of a DNA strand you must replace eachcharacter with its complement. For example, ATCGG is the complement of TAGCC andCCC is the complement of GGG. Your program must show a DNA of a predefined lengthto the player and ask for its complement.2. Find the reversed DNA strand: the order of the characters in a DNA strand should bereversed. Examples: GCTAA is the reverse of AATCG and AA is the reverse of AA. Yourprogram must show a DNA of a predefined length to the player and ask for the reversedstrand.3. Find the compressed DNA strand: all repeated characters in a DNA strand should bereplaced by the number of repeats followed by that character once. For example, 2C3ATis the compressed…
