### CS61A HOMEWORK 8

For the most part, this course is not about learning Python, the language, but instead, we focus on big computer science ideas. OK autogrades programming assignments, facilitates submission, composition feedback, and analytics for your class. Check that you have successfully submitted your code on okpy. Question 1; Question 2; Question. This is a review of all of the material. Solutions for Homework 3.

Implement a procedure called ordered? For the most part, this course is not about learning Python, the language, but instead, we focus on big computer science ideas. To fix this, we need to use tail recursion! As an example, consider a call to fact 5 Shown with Scheme below. For example, cons 1 cons 2 3 would print as 1 2. Instead of a variable, we introduce a new parameter to keep track of the total.

homewokr Try writing the function iteratively in Python, then convert into a tail recursive Scheme function. For this set of problems. The Structure and CS Define intersectwhich returns a set containing only values that appear in both sets s and t.

## Homework Questions

I am taking CS61A next spring and want to be extra prepared It raised and spent I should be doing my 61A homework after getting owned on the midterm. Check that you have successfully submitted your code on okpy. Sets as Ordered Lists Q6: Write a function that takes. Instead of a variable, we introduce a new parameter to keep track of the total. Because Scheme supports tail-call optimization note that Python does notit knows when it no longer needs to keep around frames because there is no further calculation to do.

Conditional expressions are evaluated as follows. This is a review of all of the material. However, before calculating this product, we must wait for the call to fact 4. Structure and Interpretation of Computer Programs Decide which of version 1 or 2 has better composition: We have provided a starter file for the questions below. Implement the procedure nodotswhich takes a nested list of numbers that may not be well-formed and returns a nested list with the same content and structure, but which does not have any dots when displayed.
