Consider the following frequent 3-sequences:
< {1, 2, 3} >, < {1, 2}{3} >, < {1}{2, 3} >, < {1, 2}{4} >, < {1, 3}{4} >, < {1, 2, 4} >, < {2, 3}{3} >, < {2, 3}{4} >, < {2}{3}{3} >, and < {2}{3}{4} >. (a) List all the candidate 4-sequences produced by the candidate generation step of the GSP algorithm. (b) List all the candidate 4-sequences pruned during the candidate pruning step of the GSP algorithm (assuming no timing constraints). (c) List all the candidate 4-sequences pruned during the candidate pruning step of the GSP algorithm (assuming maxgap = 1).
Answer the following statements true (T) or false (F)
1) There are four basic ways to traverse a tree, and they are all implemented recursively. 2) A decision tree cannot be used as the basis for an expert system. 3) In an inorder traversal, the elements of a tree are visited in order of their distance from the root. 4) In a postorder traversal, the root is the last element visited in the tree. 5) Recursive methods that work with binary trees are often implemented with a private support method.
