Coloring Tree Hackerrank

Given a tree with all nodes colored, find the number of distinct colors rooted at a given node. HackerRank Coloring Tree problem solutionIn this HackerRank Coloring Tree problem solution, you are given a tree with N nodes with every node being colored. A color is represented by an integer ranging from 1 to 109.

You are required to color the tree with r colors. Cost of coloring a node with color i is A i. Also, for each edge, such that the nodes at its end point are colored with the same color i, there is an additional cost of B i.

You are required to find the minimum cost to color all the nodes of the tree. Input The first line of the input contains 2 integers n. Test your knowledge with our Tree Coloring practice problem.

Last weekend (March 1-2) the 2014 HackerRank 101 Hack took place. In particular, a problem named Coloring Tree was present. Basically, the problem gives you a tree where each vertex is assigned a color and asks you queries where you have to find the number of distinct colors in a particular subtree.

I was giving hackerrank test for some company recently and came across the following question. I searched and found out that it's unsolvable (NP-hard) for the given constraint. Please let me know if you know how to solve this one.

Problem Calculate the number of ways to color an N * M grid using K colors. Adjacent squares in the grid should have different colors. Squares are considered.
