Contact Lenses: You are building an expert system that can help optometrists decide on what type of contact lens a patient should be prescribed. The table below shows the data regarding previous patient characteristics and their prescribed lenses.

Build two classification models - one with Decision Trees and the other with Naive Bayes - from this data and predict the recommended lens of the following patient:

Notice: In class, we only built the Root Node of the example decision tree. To complete the classification, you need to build the remaining layers as well. Please show all your calculations.
