We begin by restating what's being asked: you need to calculate the new centroid (x, y, z) of Cluster 2 after the first iteration of K-Means with K=2, using the Manhattan distance, and with seed centroids at (1, 0, 0) and (0, 1, 1). The required result should be the mean of all points assigned to Cluster 2, rounded to 1 decimal place where needed, and expressed as comma-separated values without brackets or spaces.

Key step in K-Means: after the first assignment step, each data point is allocated to the nearest centroid according to the distance metric (here, Manhattan distance). The new centroid for a cluster is then computed as the coordinate-wise average (the mean) of all points assigned to that cluster.

What is missing: the actual table of results from the first iteration is not provided in the prompt. Without the list of data points and which ones were assigned to Cluster 2, we cannot compute the mean of x, y, and z for that cluster. The computation requires:
- The set of points that were assigned to Cluster 2 after the first iteration.
- Each point's coordinates (x_i, y_i, z_i).
- Then we would calculate new_x = (sum of x_i for points in Cluster 2) / N, new_y = (sum of y_i) / N, new_z = (sum of z_i) / N, where N is the number of points in Cluster 2.

If the data were available, the next steps would be:
- Identify all points assigned to Cluster 2 using the Manhattan distance to the two seed centroids, (1, 0, 0) and (0, 1, 1).
- Compute the arithmetic mean of the x-coordinates of those points to get the new x-coordinate of the centroid.
- Compute the arithmetic mean of the y-coordinates to get the new y-coordinate.
- Compute the arithmetic mean of the z-coordinates to get the new z-coordinate.
- Round each coordinate to 1 decimal place if needed, and report them as a, b, c separated by commas without spaces or brackets.

Because the problem statement does not include the actual table of results or the list of points assigned to Cluster 2, any specific numeric answer would be speculative. If you can provide the first-iteration assignment table (the points in Cluster 2), I can perform the exact centroid calculation step by step.
