The Collatz conjecture, named after Lothar Collatz who introduced the idea is a perfect example of a mathematical problem that cannot be solved by mathematics and the tools available within the domain and scope of mathematics of today.

It goes a little like this:

$${\displaystyle f(n)={\begin{cases}{\frac {n}{2}}&{\text{if }}n\equiv 0{\pmod {2}}\\[4px]3n+1&{\text{if }}n\equiv 1{\pmod {2}}.\end{cases}}}$$

it's a nice little conjecture to turn into a program, so I decided to write it in YASS to try and demonstrate this based on the above syntax:

YASS
function f ($n) if($n % 2 == 0)
$n =$n / 2
else
$n = ($n * 3) + 1
end if

return $n end function$n = input("Please insert a start number")

$iterations = 0 print($n)
while($n != 0 and$iterations < 5)

$n = f($n)

print($n) if($n == 1)
\$iterations++
end if
end while
