Q1: Paths List. (Adapted from Fall 2013) Fill in the blanks in the implementation of paths, which takes as input two positive integers x and y. It returns a list of paths, where each path is a list containing steps to reach y from x by repeated incrementing or doubling. For instance, we can reach 9 from 3 by incrementing to 4, doubling to 8 ...Part A: Implement sum_tree, which returns the sum of all the labels in tree t. Part B: Implement balanced, which returns whether every branch of t has the same total sum and that the branches themselves are also balanced.

For a given integer, the digit distance is the sum of the absolute differences between consecutive digits. For example: The digit distance of 6 is 0.; The digit distance of 61 is 5, as the absolute value of 6 - 1 is 5.; The digit distance of 71253 is 12 (6 + 1 + 3 + 2).; Write a function that determines the digit distance of a given positive integer.(Fall 2021) Ben's Scheme Cheat Sheet (Spring 2021) Study Guide: Scheme (Fall 2019) Shayna's Scheme Guide (Fall 2017) Minilecture: Scheme Intro (Spring 2015) Max's Scheme Lists Video.

Playing the game. The game can be run in two modes: as a text-based game or using a graphical user interface (GUI). The game logic is the same in either case, but the GUI enforces a turn time limit that makes playing the game more exciting. The text-based interface is provided for debugging and development.Implement the function ordered_digits, which takes as input a positive integer and returns True if its digits, read left to right, are in non-decreasing order, and False otherwise. For example, the digits of 5, 11, 127, 1357 are ordered, but not those of 21 or 1375. def ordered_digits(x): """Return True if the (base 10) digits of X>0 are in non ...
When given an input such as (+ 1 2) , there are two main steps we want to take. The first part of interpreting expressions is taking the input and breaking it down into each component. In our example, we want to treat each of (, +, 1, 2, and ) as a separate token that we can then figure out how to represent. This is called lexical analysis, and ...Q3: Lambdas and Currying. We can transform multiple-argument functions into a chain of single-argument, higher order functions by taking advantage of lambda expressions. For example, we can write a function f (x, y) as a different function g (x) (y). This is known as currying. Each homework assignment counts for 2 points, so in this case you will receive the full 2 points for homework. Remember that every incorrect question costs you 1 point, so a 5.0/6.0 on this assignment will translate to a 1.0/2.0 homework grade for this assignment.

Looking for something to keep you warm and comfortable Head TAs additionally manage a broader component of the course, such as logistics, content, software, office hours, etc. Some TAs have access to sensitive information, and so are listed first. A TA with the "cs61a@" tag has access to the [email protected] inbox, and so will see (and likely respond to) anything that goes through that email. Note that exams from Spring 2020, Fall 2020, and Spring 2021 gave students access to an interpreter, so the question format may be different than other years. Regardless, the questions below are good problems to try without access to an interpreter. Fall 2019 MT1 Q3: You Again [Higher Order Functions] Grading basis: letter.

I once heard that it's an amazing cs course and it's very helpful for those who are new to programming, so I decided to take this course to see if I could learn something new. To be honest, this is the best introductory computer programming class I've ever taken. Q1: Paths List. (Adapted from Fall 2013) Fi zzzqiii/CS61A-Fall-2021.
