Please implement a delete function for a two-three -four tree in the following code (Please keep the names the same, as there is a script used to test the codes):
public class TwoFourTree {// Internal class representing each node in the 2-4 Tree private class TwoFourTreeItem { int values =1; // Number of values stored in this node int value1=0, value2=0, value3=0; // Node can store up to three values boolean isLeaf = true; // True if this is a leaf node TwoFourTreeItem parent = null; // Parent node TwoFourTreeItem leftChild = null, centerChild = null, rightChild = null; // Children nodes TwoFourTreeItem centerLeftChild = null, centerRightChild = null; // Additional children for 3-node splitting // Constructor for creating a 2-node with one value public TwoFourTreeItem(int value1){ this.value1= value1; }// Constructor for creating a 3-node with two values public TwoFourTreeItem(int value1, int value2){ this.value1= value1; this.value2= value2; this.values =2; }// Constructor for creating a 4-node with three values public TwoFourTreeItem(int value1, int value2, int value3){ this.value1= value1; this.value2= value2; this.value3= value3; this.values =3; }}// Root of the tree private TwoFourTreeItem root = null; // Function to add a value to the tree public boolean addValue(int value){ if (root == null){// If the tree is empty, create a new root root = new TwoFourTreeItem(value); return true; } return insert(root, value); // Insert the value starting from the root }// Function to check if a value exists in the tree public boolean hasValue(int value){ return search(root, value); // Search the value starting from the root }// Function to delete a value from the tree (not implemented yet) public boolean deleteValue(int value){ return delete(root, value); }// Helper function to insert a value into the tree private boolean insert(TwoFourTreeItem node, int value){ if (node.isLeaf){// If it's a leaf, we can add the value directly if (node.values ==1){// If the node has only one value (2-node) if (value node.value1){ node.value2= node.value1; node.value1= value; // Insert at the correct position } else { node.value2= value; // Insert the value as the second value } node.values =2; // Now the node is a 3-node return true; } else if (node.values ==2){// If the node is already a 3-node if (value node.value1){ node.value3= node.value2; node.value2= node.value1; node.value1= value; // Insert at the correct position } else if (value node.value2){ node.value3= node.value2; node.value2= value; } else { node.value3= value; // Insert as the third value } node.values =3; // Now the node is a 4-node return true; }}// If not a leaf, descend to the correct child node if (value node.value1){ if (node.leftChild == null){ node.leftChild = new TwoFourTreeItem(value); // Create a new left child if null } else { return insert(node.leftChild, value); // Recursively insert into the left child }} else if (node.values ==1|| value node.value2){ if (node.centerChild == null){ node.centerChild = new TwoFourTreeItem(value); // Create a new center child if null } else { return insert(node.centerChild, value); // Recursively insert into the center child }} else { if (node.rightChild == null){ node.rightChild = new TwoFourTreeItem(value); // Create a new right child if null } else { return insert(node.rightChild, value); // Recursively insert into the right child }} return true; }
The rest of the code is in the attached images ```
// Helper function to search for a value in the tree
private boolean search(TwoFourTreeItem node, int value){

} else if (node.values ==1|| value node.value2){
return search(node.centerChild, value); // Search in the center child
} else {
return search(node.rightChild, value); // Search in the right child
}
}
// Helper function to delete a value (not yet implemented)
private boolean delete(TwoFourTreeItem node, int value){
return false; // Placeholder for future deletion logic
}
// Function to print the tree in in-order traversal
public void printInOrder(){
printInOrder(root,0); // Start the print from the root
