The major advantage of using decision trees is that they are intuitively very easy to explain. They closely mirror human decision-making compared to other regression and classification approaches. They can be displayed graphically, and they can easily handle qualitative predictors without the need to create dummy variables.
As you see, you should make a habit of thinking about the time complexity of algorithms as you design them. Asymptotic analysis is a powerful tool, but use it wisely. Sometimes optimizing runtime may negatively impact readability or coding time. Whether you like it or not, an effective engineer knows how to strike the right balance between runtime, space, implementation time, maintainability, and readability.
