**Question 1:**\n* https://leetcode.com/problems/delete-nodes-and-return-forest\n\n**Question 2:**\n* Variation of https://leetcode.com/problems/evaluate-division\neuro -> dollar = 0.42 \nyard -> meter = 0.898\nYou are given an input file of currency relations as it was shown above. You have `Q` number of queries, where each query has two inputs: from and to ("euro", "pound"). As a result for that query, you need to return its relation (coefficient) between those two nodes, if there is no such relation return -1.\n\n\tNOTE:\n\t1) It\'s guaranteed that the coefficient between nodes "A" and "B" will be the same, no matter which road it takes.\n\t2) You can assume a graph as undirected.
