Data Structure Interview Questions and Answers. Techniques for making hash function. This is the binary search tree insertion and deletion c program method for computing address from a key. In this method we take only a part of the key as address.
Example Let us take some 8 digit keys and find addresses for them. Let the table size is 1. Suppose the keys are. So the address of above keys will be 7. This method is easy to compute but chances of collision are more because last two digits can be same in more than one keys. In this method the key is squared and some digits from the middle of this square are taken as address. Example Suppose that table size is 1. In this technique the key is divided into different part where the length of each part is same as that of the required address, except possibly the last part.
Example Let key is 1. Now we will add these broken parts. The sum is 1. Division Method Modulo DivisionIn Modulo Division method the key is divided by the table size and the remainder is taken as the address of the hash table.
Let the table size is n then. Let the keys are 1. So the hash address binary search tree insertion and deletion c program above keys will be 2,1.
Note Collisions can binary search tree insertion and deletion c program minimized if the table size is taken to be a prime number. Binary Trees, Data Structures and Algorithms. Trees are natural structures for representing certain kinds of hierarchical. A rooted tree consists of a set of nodes or vertices. Each arc links a parent node to one of the parents children. A special root node has binary search tree insertion and deletion c program parent.
Every other node has exactly one parent. It is possible to reach any node by following a. If arcs are considered bidirectional. The simplest kind of tree is a binary tree. We consider unrooted trees elsewhere, e. A way to think of a binary tree is that. Tree fork e tree e tree e. A binary search tree can be created so that the elements in it satisfy an ordering property. This allows elements to be searched for quickly.
All of the elements in. This article explains the concept of singly linked list data structure and provides a sample implementation in C.
Linked lists are building blocks for many other. Binary tree is the data structure to maintain data into memory of program. There exists many data structures, but they are chosen for usage on the basis of. The Tree Abstract Data Type. It is also common to use curried versions of constructors and functions. Many operations can be defined on trees. Note that these functions are binary recursive as is the definition.
Also note that a tree consisting of. Trees have many uses in computing. For example a parse tree can represent the structure of. Multiplication has a higher priority. This tree shows that abc is interpreted as ab rather than as ab. Such trees are used in compilers and other programs. Implementation of Binary Trees by Pointers and Records.
A tree data type can be implemented as a collection of records and pointers. The basic operations can create new records. Not surprisingly this tree implementation is similar. An output routine for trees is a virtual necessity. A tree can binary search tree insertion and deletion c program printed in a style like that used for lists. It is difficult to print trees down the page, because. For an example of tree output, see later sections. Parsing an input language according to a grammar is.
Here we consider a language of simple arithmetic expressions. Grammar for Simple Expression. The grammar can be read as a definition of the. The symbol can be read as is or can be replaced by. The symbol can be read as or. The names in angle brackets, such as lt exp. The string lt exp 1 is not a legal expression. The first line of the grammar can be read as. An expression is either an expression plus a term or. Note that the syntax rules are recursive. A little thought shows that an expression is a sequence of.
Similarly, a term is a sequence of operands binary search tree insertion and deletion c program by multiplication signs. An operand is either an identifier or a bracketed subexpression.
An identifier is a sequence of letters. A parser can be written using the recursive descent technique. A procedure is written to recognise. These routines are recursive, as is the binary search tree insertion and deletion c program. For example, the routine for expression. The repetitive nature of expressions and terms. A bracketed subexpression is inherently recursive. The complete parser is given below. It is moderately long but not complex.
A lexical routine, insymbol. It is followed by the parser proper consisting. Operand, Term and Exp. Note the use of mutual recursion. Various errors may be detected during parsing. If the expression is syntactically correct. There are three classic ways of recursively traversing a tree. In each of these, the left and right subtrees are. In a preorder or prefix traversal the root is visited.
In an infix traversal, the left subtree is traversed and. In a postorder or postfix traversal. This method can be used to generate postfix or reverse Polish. Given the following tree. The results of yet another method, breadth first traversal.
Note that the method given for printing a tree is. A breadth first traversal of a tree. It next visits the children, then the grand children and so on. Example Breadth First Order. The numbers indicate the order in which.
