We simply transverse across the array comparing each element with the one before it, and maintaining two counters, one for the length of current increasing sequence, and other for the length of overall maxima till this point. Any hints? Unless I'm mistaken, the question basically requires us to: Divide the tree into a number of (different) connected subsets of nodes (or sub-trees) in the tree, with at least one of the sub-trees having exactly K nodes. Let’s try to define a DP state as [math]dp(i, diff, pos)[/math] denoting the unfairness factor of a distribution considering first i integers of the given sequence. It is easy to formulate the DP when you are able to think in a recursive manner. Programming competitions and contests, programming community. ; Updated: 3 Jan 2019 is search?
