Coloring Tree Hackerrank Solution

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? Input Format The first line contains three space separated integers representing the number of nodes in the tree (N), number of queries to answer (M) and the root of the tree. In each of the next N-1 lines, there are two space separated integers (a b) representing an edge from node a to Node b and vice.

Bold Link: Solution with graphics. 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. Today when he got a tree, he colored each edge with one of either red (r) or black (b) color. 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. Here we are including all the HackerRank Algorithms problems solutions with practical program code and examples, and step-by-step explanation in Python, Java, C++, C, and JavaScript. All these problems solutions are for learning purpose.

if any change is required in these solutions or you want solution in any other programming language then please send us an email with the details. 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 color x.

Given a tree with all nodes colored, find the number of distinct colors rooted at a given node. Solving code challenges on HackerRank is one of the best ways to prepare for programming interviews.
