What do we mean by algorithm? What are the characteristics of a good and relevant algorithm?
An algorithm is "a step-by-step procedure for finishing some task'' An algorithm can be specified in many ways. For example, it can be written down in English (or French, or any other language). However, we are interested in algorithms which have been specifically specified using an appropriate mathematical formalism--such as a programming language.
Each and Every algorithm should have the following five characteristics:
1.Input characteristics: The algorithm should be taking zero or more input.
2. Output characteristics: The algorithm should be producing one or more outputs.
3. Definiteness characteristics: All the steps of algorithm should be defined unambiguously.
4. Effectiveness characteristics: A person should be able to calculate the values involved in the process of the algorithm using paper and pencil.
5. Termination characteristics: An algorithm must terminate after a finite number of steps which means it should not be infinite.
In a doubly linked list, also called as 2 way list, each node is divided into 3 parts. The first part is called previous pointer field. It contains the address of the preceding
What is Efficiency of algorithm? Efficiency of an algorithm can be precisely explained and investigated with mathematical rigor. There are two types of algorithm efficiency

The time required to delete a node x from a doubly linked list having n nodes is O (1)
a. In worst case the order of linear search is O (n/2) b. Linear search is more competent than Binary search. c. For Binary search, the array must be sorted in ascending orde
The most common way to insert nodes to a general tree is to first discover the desired parent of the node you desire to insert, and then insert the node to the parent's child list.
