In Beginning Student with List Abbreviations
I am struggling to come up with functions to remove duplicates from a list while maintaining the order of the list. one function to remove duplicates from the left, i.e. 1 2 1 3 2 4 5 -> 1 2 3 4 5 and one from the right. i.e. 1 2 1 3 2 4 5 -> 1 3 2 4 5 What are the functions for removing duplicates from each left and right side? If you need to, use helper functions and append, cond, cons, equal?, etc but not using reverse or any built-in functions. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
