Error detection and correction: cyclic redundancy check
consider the cyclic redundancy check (crc) algorithm discussed in section 5.2.3 of the text. suppose that the 4-bit generator (g) is 1001, that the data payload (d) is 1000 and that r=3.
 what are the crc bits (r) associated with the data payload of d = 1000, given that r=3?

[hint: recall from the text that in calculating the crc bits, all crc calculations are done in modulo-2 arithmetic without carries in addition or borrows in subtraction. this means that addition and subtraction are identical and both equal to the bitwise exclusive-or (xor) of the operands. if you'd like to review modulo-2 binary arithmetic, here is a nice site that provides a modulo-2 binary arithmetic calculator, and provides explanations of the calculations.]

Write a function 'music_func' that takes 3 parameters -- music type, music group, vocalist -- and prints them all out as shown in the example below. in case no input is provided by the user, the function should assume these values for the parameters: "classic rock", "the beatles", "freddie mercury". for example: input: alternative rock, pearl jam, chris cornell output: the best kind of music is alternative rock the best music group is pearl jam the best lead vocalist is chris cornell note: the print statements will go inside the for example: print("the best kind of music is"

Write a program that reads a file consisting of students’ test scores in the range 0–200. it should then determine the number of students having scores in each of the following ranges: 0–24, 25–49, 50–74, 75–99, 100–124, 125–149, 150–174, and 175–200. output the score ranges and the number of students. (run your program with the following input data: 76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189.)
