Data structure nil

What does nil mean in coding?
An explanation of nil
In Emacs Lisp, the symbol nil has two meanings.
First, it means the empty list.
Second, it means false and is the value returned when a true-or-false-test tests false. nil can be written as an empty list, () , or as nil ..
What does nil stand for in algorithm?
Null pointer (sometimes written NULL , nil , or None ), used in computer programming for an uninitialized, undefined, empty, or meaningless value..
What is nil in bst?
If the tree is nil, the key being searched for does not exist in the tree.
Otherwise, if the key equals that of the root, the search is successful and the node is returned.
If the key is less than that of the root, the search proceeds by examining the left subtree..
What is nil in data structure?
Meanwhile, in database management systems, “nil” or “null” represents unknown, missing, or unassigned values within a table or record.
Nil denotes zero-value plaintext, ciphertext, or a cryptographic key's absence in cryptography._{Apr 27, 2023}.
What is the data structure of null?
The use of null in data structures, specifically in capital letters (NULL), is used to indicate the absence of a value or the end of a list.
It is a value that is assigned to a pointer when it points to nothing, and is often used as a sentinel value to indicate the end of a list or array..
If the tree is nil, the key being searched for does not exist in the tree.
Otherwise, if the key equals that of the root, the search is successful and the node is returned.
If the key is less than that of the root, the search proceeds by examining the left subtree.
In a singly linked list, the next pointer of the last node typically points to nil , indicating the end of the list.
NIL is a special type of node which indicates the leaf nodes in the other trees like binary search trees and AVL trees.
NIL nodes helps for balancing the black height.

nil is a possible value of any data type in Clojure. nil has the same value as Java null. The Clojure conditional system is based around nil and false, with nil and false representing the values of logical falsity in conditional tests - anything else is logical truth.
