Summary: Today we explore Scheme's list data structure and some ways to use lists to make interesting images.
quick overview then mostly labday.
(list val1 val2 ... valn)
(make-list n value)
(map func lst)>. Apply a function to each element of a list.
(map drawing-transform list-of-drawings list-of-values)
(append lst1 lst2)- join two lists
(reverse lst)- just what it sounds like
(list-take lst n)- take the first n elements of a list
(list-drop lst n)- drop the first elements of a list
I usually create these pages
on the fly, which means that I rarely
proofread them and they may contain bad grammar and incorrect details.
It also means that I tend to update them regularly (see the history for
more details). Feel free to contact me with any suggestions for changes.
