# CS61A HOMEWORK 8

You will notice that it will case a maximum recursion depth error. The general form of a conditional expression is: There should be no repeated elements in the return value. One way to represent a set is by using an ordered list, where the ordering is used to speed up search although only by a constant factor. The max function can take an arbitrary number of arguments.

Implement a procedure called ordered? Extra material related to CS61A, Fridays 4: Your implementation should run in linear time in the length of the input sets. If you have any questions about using Ok, please refer to this guide. A Python implementation of this procedure is provided for your reference.

Keeping all these frames around wastes a lot of space, so our goal is to come up with an implementation of factorial that uses a constant amount of space. Wednesday July 10, Thursday. Define addwhich takes a set s and a value v as arguments. Numbers are considered nondescending if they are in a monotonically increasing sequence, that is: Implement the exp procedure using tail recursion:.

Fill in the blanks in the following function definition for adding a to the absolute value of bwithout calling abs.

## Homework Questions

Cw61a have provided a hw8. Each link below leads to a directory with a readme file containing the homework or project, a readme. Also, define unionwhich returns a set containing all values that appear in either set s or t. 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.

Structure and Homewoek of Computer Programs Due by The Python implementation of this procedure is provided for your reference. You can find the le juge et le divorce dissertation solutions in the hw Intersect and Union Define intersectwhich returns a set containing only values that appear in both sets s and t.

Mid-semester Survey is honework longer accepting responses. We notice that in Python we can do this with a while loop:. Analogously, a hailstone travels up and down homewirk the atmosphere before eventually landing on earth. One way to represent a set is by using an ordered list, where the ordering is used to speed up search although only by a constant factor. These links will point to a published google doc once the homework solution is released at least 72 hours after the deadline.

The number n will travel up and down but eventually end at 1 at least for all numbers that have ever been tried — nobody has ever proved that the sequence will terminate. In such cases, the list will print with a dot before the final item to indicate that its last two items are contained in a single pair.

Our particular version of the Scheme interpreter allows you to write True and False in place of t and fand prints boolean values as True and False.

Our particular version of the Scheme interpreter allows you to write True and False in place of t and fand prints boolean values as True and False. Sign Using conddefine a procedure sign that returns -1 for negative arguments, 0 for zero, and 1 for positive arguments: Contribute to cs61a development by creating an account on GitHub.

So, we write the following recursive procedure:.

You might find the following references useful: If no clause has a true predicate, the result is an “unspecified value”. We have provided a hw3. Monday July 7, Tuesday July 8 Reading: Solutions for Homework 3.
