When to use get MST of undirected & weighted Graph Idea maintain two sets of vertices (1: MST, 2: not visited) find cut vertex minimum weight in each loop until all vertices be included in MST 📝 cut vertex: connect vertex which connects two disjoint subsets Algorithm (1) Create key-value table (vertex - weight) , empty MST Set (2) initialize first value of key as '0' to visit first, remain key a..
