Hi, I was just wondering if we can assume that the string can only have numeric numbers (0 - 9) or do we have to implement a code for numbers greater than 9. Thank you
Can there be a word like "DIJXYILOJ"? What I mean is can there be "I" or "J" in a word where there already "IJ" is present?
? Q3 spaces and hyphens
Can we assume that all the scrabble inputs are going to be a single word with no hyphens or spaces? In other words, can expect only one word in the string?
Can you clarify by what it means, "Keep the copy of each item which is closest to the end of the list." and how can such a thing be implemented? Can you give an example in ps...
? Question 2
How am I supposed to use the helper function in my main function? I'm having a lot of trouble with this question. Can I have a hint?
? Question 3
For question 3 , can we assume the given list is non-empty?
? Test Cases
Is it okay to let the test cases exceed the 80 characters per line limit? Some of my test cases are lists that I have a hard time spacing (putting it on the next line).
For question 3, do we need to keep it as (+ 1 1 1) or we are allowed to just get 3?
Is our racket still on Beginning Student or are we at the point to change it to Beginning Student with list Abbreviations?
I noticed assignment four is due before the deadline for the concepts in module 5: Lists. Obviously completing the entire fifth module would benefit one in this assignment. How...
