List vs. tuple: what's the difference?
Step by step
Solved in 2 steps
- Lab Goal : This lab was designed to teach you more about list processing and algorithms.Lab Description : Write a program that will search a list to find the first odd number. If an odd number is found, then find the first even number following the odd number. Return the distance between the first odd number and the LAST even number. Return -1 if no odd numbers are found or there are no even numbers following an odd numberAssignment: Change the styles of ordered list and unordered listscheme: Q8: Substitute Write a procedure substitute that takes three arguments: a list s, an old word, and a new word. It returns a list with the elements of s, but with every occurrence of old replaced by new, even within sub-lists. Hint: The built-in pair? predicate returns True if its argument is a cons pair. Hint: The = operator will only let you compare numbers, but using equal? or eq? will let you compare symbols as well as numbers. For more information, check out the Scheme Built-in Procedure Reference. (define (substitute s old new) 'YOUR-CODE-HERE )

- After a tuple is created, its items can be changed. True False A tuple's items can be access by square brackets, similar to lists. True FalseWords with given shape def words_with_given_shape(words, shape): The shape of the given word of length n is a list of n - 1 integers, each one either -1, 0 or +1 to indicate whether the next letter following the letter in that position comes later (+1), is the same (0) or comes earlier (-1) in the alphabetical order of English letters. For example, the shape of the word 'hello' is [-1, +1, 0, +1], whereas the shape of 'world' is [-1, +1, -1, -1]. Find and return a list of all words that have that particular shape, listed in alphabetical order. Note that your function, same as all the other functions specified in this document that operate on lists of words, should not itself try to read the wordlist file words_sorted.txt, even when Python makes this possible with just a couple of lines of code. The tester script already reads in the entire wordlist and builds the list of words from there. Your function should use this given list of words without even caring which particular file it…Words with given shape def words_with_given_shape(words, shape): The shape of the given word of length n is a list of n - 1 integers, each one either -1, 0 or +1 to indicate whether the next letter following the letter in that position comes later (+1), is the same (0) or comes earlier (-1) in the alphabetical order of English letters.
