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.

Can you find the number of distinct colors available in a subtree rooted at the node s?

Practice the Coloring a tree problem now!You are given a tree with n nodes. 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.

He is interested in knowing how many triplets (a,b,c) of vertices are there, such that, there is atleast one edge having red color on all the three paths i.e. from vertex a to b, vertex b to c and vertex c to a. Given a tree with N nodes which initially have no color and an array color [] of size N which represent the color of each node after the coloring process takes place.

The task is to color the tree into the given colors using the smallest possible number of steps. On each step, one can choose a vertex v and a color x, and then color all vertices in the sub-tree of v (including v itself) with. You are given a tree with n nodes.

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.
