CODE EXPLANATION: Shifting list elements to the left In the Code, Above we use a user-defined function “ShiftLeft” for the required program. The program emphasizes on Shifting the elements in a list to the Left. So, This means that all the elements are shifted to the previous index value...

Bit-shift one that many places. Then divide the value of our iterator by eight to determine which octet we are manipulating, and add that list value to the result. Take this result and put it in the string in the location defined by the current bit divided by eight. Then move on to ...
