Very nice solution, guys. Two thumbs up.
And it's O(n), because you do not need to compare each pair and even do not need to sort, in order to find max(t_i). Cute!

For example inputs 50 50 110 and 50 50 2440 should give the same output. But your code doesn't. Hope it helped

Could you please explain, how it is possible to construct list Z from sample input?
Z = zip Z S
which creates structure (if I'm correct)
Z = zip zip zip zip zip ...

I think it should be
Z = zip S Z
Am I right?

Thank you in advance
