In evaluate division problem we have given some equations, in the form, A/B = k, where A and B are strings and k is a real number. Answer some queries, if the answer does not exist return -1. Example Input: equations: a/b = 2.0 and b/c = 3.0 queries: a/c …

Kruskal Algorithm

What is Kruskal Algorithm? Kruskal’s algorithm is used to find the minimum spanning tree(MST) of a connected and undirected graph. Example Graph Minimum Spanning Tree(MST) Algorithm Kruskal’s algorithm is a greedy algorithm to find the minimum spanning tree. Sort the edges in ascending order according to their weights. At every …
