module List: sig
.. end
Standard Ocaml List module with extended functionality.
Extended functionality
val range : int -> int list
range n
creates a list with values from 0 to n-1
.
val wrap : 'a -> 'a list
wrap x
returns a list that contains x
.
val cons : 'a -> 'a list -> 'a list
cons x l
appends the value x
to the list l
. x
is the
head of the result list.
val remove_fast : 'a -> 'a list -> 'a list
remove_fast x l
removes the value x
from the list l
.
val sum : int list -> int
sum l
return the sum of the elements of the int list l
.
val sumf : float list -> float
sum l
returns the sum of the elements of the float list l
.
val sum_map : ('a -> int) -> 'a list -> int
sum_map f l
applies the function f
on each element of the
int list l
and then returns the sum of the results.
val sumf_map : ('a -> float) -> 'a list -> float
sumf_map f l
applies the function f
on each element of the
float list l
and then returns the sum of the results.
val count : ('a -> bool) -> 'a list -> int
count f l
applies boolean the function f
on each element
of the list l
, and returns the number of times that f
returns
true
.
val rev_iter : ('a -> unit) -> 'a list -> unit
rev_iter f l
is the same as iter f l
, but iterates from
right to left.
val iter3 : ('a -> 'b -> 'c -> 'd) -> 'a list -> 'b list -> 'c list -> unit
iter2 f [a1; ...; an] [b1; ...; bn] [c1; ...; c_n]
calls in turn f a1 b1 c1; ...; f an bn cn]
.
val map3 : ('a -> 'b -> 'c -> 'd) -> 'a list -> 'b list -> 'c list -> 'd list
map f [a1; ...; an] [b1; ...; bn] [c1; ...; c_n]
returns the list f a1 b1 c1; ...; f an bn cn
. Not
tail-recursive.
val split3 : ('a * 'b * 'c) list -> 'a list * 'b list * 'c list
Transform a list of triples into a triple of lists:
split3 [(a1,b1,c1); ...; (an,bn,cn)]
is
([a1; ...; an], [b1; ...; bn])
. Not tail-recursive.
val transpose : 'a list list -> 'a list list
transpose m
transposes the matrix m
represented as a list
of lists.
val rem_first : 'a list -> 'a list
rem_first l
returns the tail of the list l
.
val rem_item : 'a list -> 'a -> 'a list
rem_item l i
returns a list that has the same order as the
list l
, which does not include the value i
. Not
tail-recursive.
