In python, in this part, you should write a for loop, updating the df_users dataframe. go through each user, and update their zip-code (column name zip), to safe harbour specifications: if the user is from a zip code for the which the "geographic subdivision" is less than equal to 2, change the zip code to 0otherwise, change the zip code to be only the first 3 numbers of the full zip cidedo all this re-writting the zip_code columns of the df_users dataframehints: this will be several lines of code, looping through the dataframe, getting each zip code, checking the geographic subdivision with the population in zip_dict, and settig the zip_code accordingly.

3. (6 pts) internally in the computer, with few exceptions, all numerical computation is done using binary numbers. output, however, often uses ascii, which is formed by appending 011 to the left of a bcd code. thus, an algorithm that directly converts a binary integer to a bcd integer is very useful. here is one such algorithm 1) draw lines to the left of the binary number to bound the expected bcd decades. (each decade is a group of 4 bits.) move the binary number one bit to the left. add 0011 to each bcd decade containing a binary value> 0100 repeat steps 2-3 until the last bit in the binary number has been moved into the least significant decade position. (note that when the last bit has been shifted into bcd decade, step 3 is not repeated.) read the bcd result. 2) 3) 4) 5) a) execute the algorithm for the binary number 1101101 b) execute the algorithm for the binary number 01110101110 4. (4 pts) represent the decimal number 3568 in bcd; excess-3 code; ascil; and hex.

1. before plugging in a new device to a computer you should unplug all other devices turn off the computer turn on the computer 2. many of the maintenance tools for a computer can be found in the control panel under administrative tools display personalization
