output must be

78,79,80,73,74,75,76,77,(other vales except these from 1 to 80)

Answer 1

[Andrei Bobrov]

try this is code

n = 8;
x = 77;
k = rem(x-1,n)+1;
out = [x:x+n-k,x-k+1:x-1]

Answer 2

This would be a good CODY problem:

%Parameters:
nel  = 8; %elements
x = 14;

%Engine
ypos = mod(x,nel);
val = circshift((x-ypos):(x-ypos)+nel-1,[0 -ypos])
