In the Active Parenting lessons, participants are shown videos illustrating different parenting concepts. For example, one video shows a parent give a child a choice between reading a book about farms or a book about fairies. This is intended to show the “method of choice” concept.  Which of Merrill’s principles of instruction does this best represent?

What role is BEST represented by the approach Thomas is taking as a parent educator?

Standard disclaimer: use the algorithms from class, such as DFS, Explore, BFS, Dijkstra’s (using min-heaps), SCC, Kruskal’s, Prim’s etc., as a blackbox subroutine for your algorithm. Make sure to explain your algorithm in words (no pseudocode!), explain the correctness of your design, and state and analyze its running time. Faster – and correct – solutions worth more credit. Design an algorithm to solve the following problem:Input: a connected, undirected, weighted graph G = (V,E), and a subset U of the vertices  .Output: A spanning tree of G of minimal weight with the property that all the vertices in U are leaves. Note that there may be other leaves in the optimal tree and it isn’t necessarily a MST of G.
