What does "end" mean there? Does it mean to quit the program? If so, just use return instead of end.

To exponentiate use ^

if LB^(k-1)== N
    return;
end

yes end means quit the problem. But (k) or (k-1) don't represent the exponential values. It is just a representation that LB gets values according to the change of k.

Then use LB(k-1)
