Shape-Machine
Shape-Machine is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
Task
- Get user input and store in a variable/stack
- Add 3 to the input and multiply it by 0.86 and then output it
- Now reapeat the previos step
- And after the number stops doing the second step you can halt the loop and count how many times did the operation happened (optional)

a=int(input())
while True:
a += 3
a *= 0.86
print(a)
Raku
my $input = (+prompt()).FatRat;
my $previous = 0.FatRat;
my $count;
my $places = 36;
loop {
$input += 3;
$input ×= .86;
last if $previous.substr(0,$places) eq $input.substr(0,$places);
++$count;
say ($previous = $input).substr(0,$places);
}
say "$count repetitions";
- Output with a 4 fed in at the prompt:
