Array.Fill(x, v);x = vThis is an array assignment with a scalar value.
func fill[T any](x []T, v T) {
for i := range x {
x[i] = v
}
}fill is generic, it works for any type parameter T
for i := range x {
x[i] = v
}for i := Low(x) to High(x) do x[i] := v;my @x = (undef) x $n;
foreach (@x) { $_ = $v }Create a list with $n elements, each initialized to undef. Then assign $v to each element.
my @x = ($v) x $n;This defines a new list (@x) and sets $n elements of it to $v. The list grows to length $n. The x operator in this context repeats the left operand $n times.
set_all_elements_to_same_value(X, V) :-
length(X, Length),
length(FilledList, Length),
maplist(=(V), FilledList, X).x[:] = [v] * len(x)x.fill(v)
