A stream of data is received and needs to be reversed. Each segment is 8 bits long, meaning the order of these segments needs to be reversed, for example: 11111111 00000000 00001111 10101010 (byte1) (byte2) (byte3) (byte4) should become: 10101010 00001111 00000000 11111111 (byte4) (byte3) (byte2) (byte1) The total number of bits will always be a…
