this solution doesn't work for this case
returnAscending(1,2,3,10,50)
// '11023450'

1. The result should be also a string. FORTH does not support arbitrary precision arithmetic. For example, the result of

s" 10000000000000000000000000000000000000000"
s" 10000000000000000000000000000000000000000"
STRSUM

should be "20000000000000000000000000000000000000000"

2. No random tests.

Done.

Added static and random tests.

Done.

Are you able to improve your translation using @monadius suggestions?

Thanks! Approved.

I see now. This is pretty strange. Maybe Codewars bug?

It didn't crash, that's the point. Take a look at the output.

Bug is in this line:

printLn (bar [1])

bar is partial function, which means it does not handle all possible inputs. It does handle only []. You pass [1] to it and get runtime crash.

Why not

int manhattan_distance(int x1, int x2, int y1, int y2);

?

C translation is ready! Please review and approve.

Function should take one number.

Cool!

Nice!
Didn't think of that.
