If the optimal answer requires you to sleep the full time for the last time you can sleep, your code won't calculate it.

You can see in the editorial's code as well that their inner loop is j <= n, but yours is j <= i, with i < n.

For a shorter example of this case, try this:

3 24 20 20
20 14 10
