hi there,
now I am trying to use octave to do the hackerrank test, but everytime I click on the 'Run code' button, it always says that 'no response on stdout', here is the code and note:
# Enter your code here. Read input from STDIN. Print output to STDOUT
a = stdin;
pivot = a(1);
equal = pivot;
left = a(a<pivot);
right = a(a>pivot);
stdout = [left equal right];
Does anyone knows this? Many thanks!

Weiqian - if you need exactly one space between each character then perhaps try something like
printf('%d', b(1));
for k = 2:length(b)
printf(' %d')
end
instead of disp.
