Identify the error in the following algorithm to search for a node in the singly-linked list of students. ListSearch(students, key) { curNode = students⇢head while (curNode is null) { if (curNode⇢data == key) { return curNode } curNode = curNode⇢next } return null } Group of answer choices   The if condition should be if (curNode⇢data != key).   The statement curNode = students⇢head should be curNode = students⇢tail.   The statement curNode = curNode⇢next should be curNode = students⇢head.   The while condition should be while (curNode

Please fill in the code gaps if possible. This problem has been giving me trouble. Any help is appreciated.  public class Node {       private String element; // we assume elements are character strings         private Node next;  /* Creates a node with the given element and next node. */ public Node(String s, Node n) {  //fill in body  }  /* Returns the element of this node. */ public String getElement() {  //fill in body  }  /* Returns the next node of this node. */ public Node getNext() {  //fill in body  }  // Modifier methods:  /* Sets the element of this node. */ public void setElement(String newElem) {  //fill in body  }  /* Sets the next node of this node. */ public void setNext(Node newNext) {  //fill in body  } }

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.…
