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?

HackerRank Data Structures Solutions This repository contains solutions to the Data Structures domain part of HackerRank. The Data Structures Domain Falls under a broader Problem Solving Skill Set in HackerRank which consists of both Data Structures and Algorithms.
The Data Structures Domain is further Divided into the following sub. 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. 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.
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.
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. HackerRank Solutions in Python3.

HackerRank Solutions Over the course of the next few (actually many) days, I will be posting the solutions to previous Hacker Rank challenges. The page is a good start for people to solve these problems as the time constraints are rather forgiving.
The majority of the solutions are in Python 2. Some are in C++, Rust and GoLang.
