Question Discussion & Solution

Fawn is young one of deer.

Similarly, Larvae are young one of insect.

Key Points Doubly linked list:
A doubly linked list is a linked data structure that consists of a set of sequentially linked records called nodes. Each node contains three fields: two link fields and one data field.
Binary tree:
A binary tree is a tree data structure in which each node has at most two children, which are referred to as the left child and the right child.

Linked list:

A linked list is a linear collection of data elements whose order is not given by their physical placement in memory. Instead, each element points to the next. It is a data structure consisting of a collection of nodes that together represent a sequence.

Queue:

A queue is a collection of entities that are maintained in a sequence and can be modified by the addition of entities at one end of the sequence and the removal of entities from the other end of the sequence.

A Doubly linked list is the efficient data structure to insert/delete a number in a stored set of numbers.

Hence the correct answer is the Doubly linked list.

Concept

The javac command in Java compiles a program from a command prompt.

It reads a Java source program from a text file and creates a compiled Java class file.

Syntax

javac filename [options]

For example, to compile a program named Abc.java, use this command:

javac Abc.java

Concept:

• Electric current is the rate of flow electric charge or free Electrons in a definite direction through any section of wire. Its SI unit is ampere(A).
• The direction of the conventional current corresponds to the direction of positive charge which is from higher potential(positive) to lower potential(negative).

I = Q / t

I is current, Q is charge, t is time

Explanation:

Q = I t

So Charge is the product of current and time.

Unit of current is Ampere, and unit of time is an hour. 

So, Amount of charge or Quantity of electricity is Ampere-hour 

The correct answer is ALGORITHM.

Key Points

• An algorithm is a specific procedure for solving a well-defined computational problem.
• The development and analysis of algorithms are fundamental to all aspects of Computer Science like AI, databases, graphics, networking, OS, etc.
• Algorithm development is more than just programming.
  • It requires an understanding of the alternatives available for solving a computational problem.
  • It includes the hardware, networking, programming language, and performance constraints that accompany any particular solution.

Additional Information

• An official language comprising a collection of instructions that produce different kinds of output is a programming language.
• In computer science, programming languages are used to implement algorithms.
• Most of the languages of programming consist of computer instructions.
