You are given both the Post-order traversal and an in-order traversal for aunique binary tree.Post-order traversal: F A C D B EIn-order traversal: A F E C B D • Draw the unique tree defined by those traversals.• Write down the corresponding pre-order traversal for that tree.
You are given a weighted tree T.(As a reminder, a tree T is a graph that is connected and contains no cycle.) Each node of the tree T has a weight, denoted by w(v). You want to select a subset of tree nodes, such that weight of the selected nodes is maximized, and if a node is selected, then none of its neighbors are selected.
