Is it possible to solve Uva 11790 using O(n log k) LIS? I kept getting WA using O(n log K) LIS, so i change to O(n^2) and get accepted. The problem's constraint is not clear though :(

If you have a correct solution, you can make a stress test and find a test where it's wrong.
It is possible to solve problem in N Log N using segment tree with queries Add(left = X, right = n, value = DX) and GetMax(left = 0, right = X). You don't need LIS.
