Problem 4. (5 points) IIandling real valued (numerical) features is totally different from categorical features in splitting nodes. This problem intends to discuss a simple way to decide good thresholds for splitting based on numerical features. Specifically, when there is a numerical feature in data, an option would be treating all numeric values of feature as discrete, i.e., proceeding exactly as we do with categorical data. What problems may arise when we use a tree derived this way to classify an unseen example
