We decide to learn a decision tree as described in class. As in class, when the decision tree splits on the real-valued features, it puts the split threshold halfway between the data points on either side of the highest-scoring split. For example, if we first split on x2, the algorithm would choose to
split at 72=1, which is halfway between the data at x2=0 and 72=2.
