For every cut we make, let's greedily cut the maximum amount of paper we can. Until we have more pieces of paper than $K$ $K$ , we will always double the amount that we currently have with each cut. Once we have more than $K$ $K$ , we can only obtain $K$ $K$ pieces more with each cut, so we can use division to find the remaining cuts needed.

Time Complexity: $\mathcal{O}(\log \min(N, K))$ $O (\log min (N, K))$
