Why in my pc showing correct but not in this
@Sumit, you are probably using a function from a toolbox (e.g. statistics toolbox) that is not available to Cody.
The test suite throws errors where but I get correct answers when I run.
function y = fcn(n,k)
y = size(combntns(1:n,k),1);
Let me import my Statistics Toolbox!
