Jan 22, 2017 at 13:56 comment added Anton Thanks a lot for your answer. I think there is something wrong with indexing. Did you mean to write $i_{t-1}$ instead of $i_{k-1}$ at the beginning? Also, at the end, I suspect that you mean $i_{n-k}=0$ and not $i_k=0$.
Jan 22, 2017 at 13:47 comment added Anton Also, do you think the answer would change drastically if I demand $i_r \neq 0$ and $i_1=1$? Because this is the setup in which I am mostly interested in. Your answer was quite surprising to me, as I would expect (at least in my setup) that the upper bound on $t$ is of the form $cn/k$, where $c$ is a constant.
