#Reversing a list# 1. How would you define an operation to reverse a list? (Don't peek at the [[lambda_library]]! Try to figure it out on your own.) Choose whichever implementation of list you like. Even then, there are various strategies you can use. (See [[hints/Assignment 4 hint 1]] if you need some hints.) #Comparing lists for equality# #Mutually-recursive functions# #Enumerating the fringe of a leaf-labeled tree# [[Implementing trees]]
