@sputter(t:tab, p:float, n:numeric)
is an impure function returning a new tab of length n
. This tab is
filled as follows:
-
The process starts with a current value initialized with the first element in
t
. -
Successively, for each element \(e\) in the result, a random number \(p'\) between 0 and 1 is compared with
p
:-
if \(p'\) it is lower than
p
, then \(c\) becomes the value of \(e\) and the element next \(e\) is processed. -
If \(p'\) it is greater than
p
, then \(c\) takes the value of the next element int
, this new value becomes the value of \(e\) and the element next \(e\) is processed.
-
Not that this function is impure as it returns a different result for each invocation. For example:
@sputter([1, 2, 3, 4, 5, 6, 7, 8, 9, 10], 0.5, 16)
can return
→ [ 1, 1, 1, 1, 1, 2, 3, 4, 5, 6, 6, 6, 7, 8, 8, 9 ] → [ 1, 2, 3, 3, 4, 5, 6, 7, 8, 8, 9, 9, 9, 9, 10 ] → [ 1, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 4, 5, 5, 5 ]
