(require mzlib/list) | package: compatibility-lib

> NOTE: This library is deprecated; use racket/list, instead.

The mzlib/list library re-exports several functions from scheme/base and scheme/list:

> cons?
> empty?
> empty
> foldl
> foldr
> remv
> remq
> remove
> remv*
> remq*
> remove*
> findf
> memf
> assf
> filter
> sort

> procedure (first v) → any/c
> v : pair?
> procedure (second v) → any/c
> v : (and/c pair? ....)
> procedure (third v) → any/c
> v : (and/c pair? ....)
> procedure (fourth v) → any/c
> v : (and/c pair? ....)
> procedure (fifth v) → any/c
> v : (and/c pair? ....)
> procedure (sixth v) → any/c
> v : (and/c pair? ....)
> procedure (seventh v) → any/c
> v : (and/c pair? ....)
> procedure (eighth v) → any/c
> v : (and/c pair? ....)

Accesses the first, second, etc. elment of “list” v. The argument need not actually be a list; it is inspected only as far as necessary to obtain an element (unlike the same-named functions from scheme/list, which do require the argument to be a list).

> procedure (rest v) → any/c
> v : pair?

The same as cdr.

> procedure (last-pair v) → pair?
> v : pair?

Returns the last pair in v, raising an error if v is not a pair (but v does not have to be a proper list).

> procedure (merge-sorted-lists lst1 lst2 less-than?) → list?
> lst1 : list?
> lst2 : lst?
> less-than? : (any/c any/c . -> . any/c)

Merges the two sorted input lists, creating a new sorted list. The merged result is stable: equal items in both lists stay in the same order, and these in lst1 precede lst2.

> procedure (mergesort lst less-than?) → list?
> lst : list?
> less-than? : (any/c any/c . -> . any/c)

The same as sort.

> procedure (quicksort lst less-than?) → list?
> lst : list?
> less-than? : (any/c any/c . -> . any/c)

The same as sort.
