Engineering Data Structures and Algorithms The tree below resulted from inserting 9 numbers into an initially empty tree. No deletes were ever performed. Below the tree, select all the numbers that could have potentially been inserted third.A minimum spanning tree ( MST) or minimum weight spanning tree is a subset of the edges of a connected, edge-weighted undirected graph that connects all the vertices together, without any cycles and with the minimum possible total edge weight. [1] That is, it is a spanning tree whose sum of edge weights is as small as possible. [2] Rooted Tree I The tree T is a directed tree, if all edges of T are directed. I T is called a rooted tree if there is a unique vertex r, called the root, with indegree of 0, and for all other vertices v the indegree is 1. I All vertices with outdegree 0 are called leaf. I All other vertices are called branch node or internal node.
