replicate n x is a list of length
n with
x the value of every element. It is an instance of the more
general
genericReplicate, in which
n may be of any
integral type.
Examples
>>> replicate 0 True
[]
>>> replicate (-1) True
[]
>>> replicate 4 True
[True,True,True,True]
O(n) replicate n x is a ByteString of length
n with
x the value of every element. The following
holds:
replicate w c = fst (unfoldrN w (\u -> Just (u,u)) c)
O(n) replicate n x is a ByteString of length
n with
x the value of every element. The following
holds:
replicate w c = unfoldr w (\u -> Just (u,u)) c
This implementation uses

O(n) replicate n x is a ByteString of length
n with
x the value of every element.
O(n) replicate n x is a ShortByteString of
length
n with
x the value of every element. The
following holds:
replicate w c = unfoldr w (\u -> Just (u,u)) c
Produce a finite stream consisting of n copies of the given value.
Subject to fusion
Replicate a single value the given number of times.

replicate n x is a
DList of length
n with
x as the value of every
element.
<math>(
n).
replicate obeys the law:
toList (replicate n x) = replicate n x
Repeat an element several times.
replicate n x is a sequence of length
n with
x as the value of every element.
> replicate 10 a :: Text
"aaaaaaaaaa"
Replicate a
ShortText.
A repetition count smaller than 1 results in an empty string result.
>>> replicate 3 "jobs!"
"jobs!jobs!jobs!"
>>> replicate 10000 ""
""
>>> replicate 0 "nothing"
""
length (replicate n t) == max 0 n * length t
Replicate a byte n times.
Repeat the byte sequence over and over. Returns empty chunks when
given a negative repetition count.
Generate a structure with the specified length with every element set
to the item passed in. See also

>>> replicate n = Stream.take n . Stream.repeat
Generate a stream of length
n by repeating a value
