CSE 1729 – Introduction to Principles of Programming October 23, 2016 Problem Set 6 1. There are a number of equality functions in Scheme: =, eq?, eqv?, equal? for example, but none of them “do it all” that is, work for symbols, numbers, and lists. For example, none of these will say #t when comparing […]

CSE 1729 – Introduction to Principles of Programming October 11, 2016 Laboratory Assignment 6 Ob jectives • Work with lists, pairs, and a defined data type. Activities In this lab, you will • define a datatype and some associated functions for complex numbers that you represent using pairs. • write some functions that manipulate lists,

CSE 1729 – Introduction to Principles of Programming Due October 16, 2015 Problem Set 5 – revised One list is a prefix of another if the other list has the same values starting from the beginning, and potentially more. For example, ’(1 2) is a prefix of ’(1 2 3 4), and also a prefix

CSE 1729 – Introduction to Principles of Programming September 25, 2016 Problem Set 3 Note: this week’s homework requires the use of the random function, which is defined in the Racket dialect of SCHEME, but not in R5RS. For this week’s homework, therefore, you will need to choose Racket as your language. You can do

; CSC104 Project #1 ; Classical encryption project ; Due: 10 p.m., October 28 ; (subject to class vote October 21) ; ; tools for reading from files and web pages (require 2htdp/batch-io) (require net/sendurl) ; ; This project involves two classical encryption algorithms. ; The techniques are called “classical” because they were made ;

CSE 1729 – Introduction to Principles of Programming Due October 2, 2016 Problem Set 4 Note: Whenever we use the terms iterative process or iterative form, we are talking about tail- recursive code. When we use the terms recursive process or recursive form we are talking about code that is not tail-recursive. Both iterative and

CSE 1729 – Introduction to Principles of Programming November 29, 2016 Laboratory Assignment 12 Ob jectives • Program in “signal-processing” style • Work with streams • Write and use some stream tools Activities To effectively write stream code you will need the Scheme primitives to deal with the stream data type. Add the following code

CSE 1729 – Introduction to Principles of Programming Due September 18, 2016 Problem Set 2 For this assignment, you will hand in 1 document, a Racket file. You will use the same labeling convention as in Problem Set 1. Remember: code questions should always include at least two test cases. Recall from class the definition

CSE 1729 – Introduction to Principles of Programming November 1, 2016 Laboratory Assignment 9 Ob jectives • Work with symbol frequencies in lists • Work with heaps • Learn a new way to sort Activities Define a Scheme function (num-occurs sym lst), that takes two parameters: a symbol sym and a list lst; it evaluates
