WebMar 24, 2024 · For example, we choose A, now D,B and E are options for making an edge. We connect the least weighted edge possible out of the given options, which is 2, from A to B. Now since B is a chosen vertex, all the adjacent vertices are options. D,E,C,G and F are options for edges. WebExample: Implementation – Adjacency Matrix. Create mst[] to keep track of vertices included in MST. Create key[] to keep track of key value for each vertex. Which vertex will be included next into MST will be decided based on the key value. Initialize key for all vertices as MAX_VAL except the first vertex for which key will 0. WebBelow we have the complete logic, stepwise, which is followed in prim's algorithm: Step 1: Keep a track of all the vertices that have been visited and added to the spanning tree. Step 2: Initially the spanning tree is empty. Step 3: Choose a random vertex, and add it to the spanning tree. This becomes the root node. dna vaccine risks
