We can cluster in one dimension as well as in many dimensions. In this problem, we are going to cluster numbers on the real line. The particular numbers (data points) are 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100. We use the K-means clustering algorithm, with the number of clusters K = 2. You can verify easily that no matter which two points we choose as the initial centroids, some prefix of the data will go into the cluster of the smaller and the remaining suffix goes into the other cluster. As a result, there are only nine different clusterings that can be achieved, ranging from {1}{4, 9, ... 100} through {1, 4, ..., 81}{100}.
We then go through a reclustering phase, where the centroids of the two clusters are recalculated and all points are reassigned to the nearer of the two new centroids. For each of the nine possible clusterings, calculate how many points are reclassified during the reclustering phase. Identify which of the following pair of initial centroids results in exactly one point being reclassified.
A) 1 and 25
B) 36 and 64
C) 9 and 49

What are compression artifacts? 1) visible defects in the picture caused by the nature of the compression algorithm. 2) numbers that tell a web server how much to compress a picture for faster transmission. 3) invisible defects in the picture preserved by lossless compression. 4) numbers that tell a photo editing program how much to compress a picture for faster transmission.

Write a method that accepts a string object as an argument and returns the number of words it contains. for instance, if the argument is "four score and seven years ago", the method should return the number 6. demonstrate the method in a program that asks the user to input a string and then passes that string into the method, printing out whatever the method returns.
