Given N gold wires with lengths, find minimum cost to assemble all wires into a single wire.

• Only two adjacent small wires can be assembled at a time

• Cost of forming is the sum of their length

• Use dynamic programming to find minimum cost

• Example: N=4, lengths=[2,3,4,5], minimum cost=29

Decode the given code to find the code for 'ONLINE'.

• Identify the pattern in the given code

• Rearrange the letters of 'ONLINE' accordingly

• Replace each letter with its corresponding code

Program to print all prime numbers in a given range.

• Take input for the range of numbers

• Loop through the range and check if each number is prime

• If a number is prime, print it

• A number is prime if it is only divisible by 1 and itself

One deadlock algorithm is the Banker's algorithm.

• Banker's algorithm is used to avoid deadlock in a multi-process system.

• It works by checking if a request for resources will leave the system in a safe state.

• If the request will not leave the system in a safe state, it is denied.

• The algorithm keeps track of available resources and the maximum resources each process can request.

• It also keeps track of the resources currently allocated to each process.

• If a process requests resource...read more

A foreign key is a column or set of columns in a database table that refers to the primary key of another table.

• It establishes a link between two tables.

• It ensures referential integrity.

• It helps in maintaining data consistency.

• It can be used to join tables in a query.

• Example: A 'customer' table may have a foreign key that refers to the 'order' table's primary key.

Exceptions are unexpected events that occur during program execution.

• Exceptions are used to handle errors and prevent program crashes.

• They can be caused by a variety of factors, such as invalid input or resource exhaustion.

• Examples of exceptions include NullPointerException, ArrayIndexOutOfBoundsException, and IOException.

• Exception handling involves catching and handling exceptions using try-catch blocks.

• Unchecked exceptions do not need to be declared in the method signature,...read more

Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.

• Inheritance allows for code reuse and promotes a hierarchical organization of classes.

• The existing class is called the superclass or parent class, while the new class is called the subclass or child class.

• The subclass inherits all the properties and methods of the superclass, and can also add new properties and methods or override existing ones....read more

finally keyword is used in try-catch block to execute a block of code regardless of the exception thrown or not.

• finally block is optional and can be used after catch block

• It is used to release resources like database connections, file handles, etc.

• It is executed even if there is a return statement in try or catch block

• Example: try { //code } catch(Exception e) { //code } finally { //code }
