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.

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 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.

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.
