Question
Given the codeword set 111111 000111 110001 101100 011010
Add another codeword to this set that has distance at least 3 to all other codewords.
Expert Solution

Step 1: Introduction
To add a codeword to the set with a minimum distance of 3 to all other codewords, we need to ensure that the Hamming distance between the new codeword and all existing codewords is at least 3. The Hamming distance is the number of positions at which two codewords differ.
Let's consider the existing codewords:
- 111111
- 000111
- 110001
- 101100
- 011010
To create a new codeword with a minimum distance of 3 to all of these, we can choose a codeword that differs in at least 3 positions from each of them. Here's one such example:
- 001001

- Up for the count def counting_series (n): The Champernowme word 1234567891011121314151617181920212223., also known as the counting series, is an infinitely long string of digits made up of all positive integers written out in ascending order without any separators. This function should return the digit at position n of the Champernowne word. Position counting again starts from zero for us budding computer scientists. Of course, the automated tester will throw at your function values of n huge enough that those who construct the Champernowne word as an explicit string will run out of both time and space long before receiving the answer. Instead, note how the fractal structure of this infinite sequence starts with 9 single-digit numbers, followed by 90 two-digit numbers, followed by 900 three-digit numbers, and so on.
