T9: On old cell phones, users typed on a numeric keypad and the phone would provide a list of words that matched these numbers. Each digit mapped to a set of 0 - 4 letters. Implement an algorithm to return a list of matching words, given a sequence of digits. You are provided a list of valid words (provided in whatever data structure you'd like). The mapping is shown in the diagram below: 1 EXAMPLE Input: 8733 Output: tree, used 4 ghi 7 pqrs 2 abc 5 jkl 8 tuv 0 3 def 6 mno 9 wxyz

Java - This project will allow you to compare & contrast different 4 sorting techniques, the last of which will be up to you to select. You will implement the following: Bubble Sort (pair-wise) Bubble Sort (list-wise) [This is the selection sort] Merge Sort Your choice (candidates are the heap, quick, shell, cocktail, bucket, or radix sorts) [These will require independent research) General rules: Structures can be static or dynamic You are not allowed to use built in methods that are direct or indirect requirements for this project – You cannot use ANY built in sorting functions - I/O (System.in/out *) are ok. All compare/swap/move methods must be your own. (You can use string compares) Your program will be sorting names – you need at least 100 unique names (you can use the 50 given in project #3) – read them into the program in a random fashion (i.e. not in any kind of alpha order). *The more names you have, the easier it is to see trends in speed. All sorts will be from…
Sorting Create a MyLinkedList class with inner Node class, data fields, and the insert(element) method. Implement a toString method to return all nodes in MyLinkedList. Implement a recursive sorting and a non-recursive sorting method.
Java Programming: Make AST Nodes: IfNode, WhileNode, RepeatNode. All will have BooleanCompare for a condition and a collection of StatementNode. ForNode will have a Node for from and a node for to. This will have to be of type Node because it could be any expression. For example: for a from 1+1 to c-6 Make parsing functions for each. Java won't let you create methods called if(), etc. parseIf() is an example of a way around that; use whatever you like but use good sense in your names. Next let's look at function calls. Each function has a name and a collection of parameters. A parameter can be a VAR variable or something that came from booleanCompare (IntegerNode, VariableReferenceNode, etc). It would be reasonable to make 2 objects - ParameterVariableNode and ParameterExpressionNode. But for this very simple and well-defined case, we can do something simple: ParameterNode has a VariableReferenceNode (for VAR IDENTIFIER) and a Node for the case where the parameter is not a VAR.…
Can you please answer this fast and with correct answer. Thankyou
8-Write a procedure that takes a tree (represented as a list) and returns a list whose elements are all the leaves of the tree arranged in right to left order or left to right. For example, ( leaves '((1 2) ((3 4) 5 )) returns (1 2 3 4 5) or (5 4 3 2 1). Then, Manually trace your procedure with the provided example.
