Students need to write a computer program to implement the decision tree learner on the data set shown in Figure $7\mathrm{.}1$ in the textbook. To complete the data set, take the user action for examples e$19$ and e$20$ as reads and skips, respectively. Use any suitable technique to split the data set into two subsets of training and testing. Students can use: Python, C$++,$ Prolog, Java or any other programming languages in which their codes can be easily tested and evaluated by the instructor.
