What is the condition for creating a new TreeNode in the code?

root == null

What happens when the element value is less than the value in the current node?

The code traverses to the left child of the current node.

What is the purpose of the 'parent' variable in the code?

To keep track of the parent node to attach the new node to

What is the purpose of a hash function in a hash table?

The purpose of a hash function is to map a key into some number in the range 0 to TableSize - 1, which is the index value for the item in the array. Signup and view all the answers

true Signup and view all the answers

What is the general strategy for hashing integer keys?

The general strategy for hashing integer keys is to use the modulo operation, i.e., Key mod TableSize. Signup and view all the answers

What is the problem with using a simple hash function for string keys?

The problem is that the number of possible keys is much larger than the space available in the table, and a simple hash function may not distribute the keys evenly. Signup and view all the answers

What is the ideal structure of a hash table?

The ideal structure of a hash table is an array of some fixed size, containing the items. Signup and view all the answers

Why is the function called a hash function?

The function is called a hash function because it 'makes a hash' of its inputs, meaning it takes the input and transforms it into a seemingly random value. Signup and view all the answers

What is the relationship between the key and the index value in a hash table?

The key is mapped into some number in the range 0 to TableSize - 1, which is the index value for the item in the array. Signup and view all the answers

What happens when `root` is `null`?

A new <code>TreeNode</code> is created with the <code>element</code>. Signup and view all the answers

What is the purpose of the `while` loop?

To locate the parent node for the new element. Signup and view all the answers

What happens if the `element` value is already in the tree?

The function returns <code>false</code> and the node is not inserted. Signup and view all the answers

How is the new node attached to the parent node?

The new node is assigned to either <code>parent.left</code> or <code>parent.right</code> depending on the comparison with <code>parent.element</code>. Signup and view all the answers

What is the final step after locating the parent node?

A new <code>TreeNode</code> is created with the <code>element</code> and attached to the parent node. Signup and view all the answers

What is the purpose of the `while (current != null)` loop in the code?

The purpose of the <code>while (current != null)</code> loop is to locate the parent node for the new node to be inserted. Signup and view all the answers

What is the significance of the `root == null` check at the beginning of the code?

The significance of the <code>root == null</code> check is to handle the case when the tree is empty, creating a new TreeNode with the element if the tree is empty. Signup and view all the answers

How does the code determine the position of the new node in the binary tree?

The code determines the position of the new node by comparing the element value to the value in the current node, and moving left or right accordingly. Signup and view all the answers

What happens when the code reaches the end of the `while` loop?

When the code reaches the end of the <code>while</code> loop, it means the correct position for the new node has been found, and the new node is created and attached to the parent node. Signup and view all the answers

What is the reason for creating a new TreeNode with the element if the tree is empty?

The reason is to initialize the tree with the first element, ensuring the tree is not empty after the insertion. Signup and view all the answers

What is the outcome if the element is already present in the binary tree?

If the element is already present in the binary tree, the code returns false, indicating that the duplicate node was not inserted. Signup and view all the answers
