Ans. 
The task is to reverse a given string containing characters from [a-z], [A-Z], [0-9], and special characters.
• Iterate through the characters of the string from the end to the beginning and append them to a new string to get the reversed string.

• Use built-in functions like reverse() or StringBuilder in languages like Java for efficient reversal.

• Ensure to handle special characters and numbers along with alphabets while rev...read more

Q2. What are the types of polymorphism in Object-Oriented Programming?
Ans. 
Types of polymorphism in OOP include compile-time polymorphism (method overloading) and runtime polymorphism (method overriding).
• Compile-time polymorphism is achieved through method overloading, where multiple methods have the same name but different parameters.

• Runtime polymorphism is achieved through method overriding, where a subclass provides a specific implementation of a method that is already defined in its super...read more

Q3. What is inheritance in object-oriented programming?
Ans. 
Inheritance is a concept in object-oriented programming where a class inherits attributes and methods from another class.
• Allows a class to inherit properties and behaviors from another class

• Promotes code reusability and reduces redundancy

• Types of inheritance include single, multiple, multilevel, and hierarchical

• Example: Class 'Car' can inherit from class 'Vehicle' to access common attributes like 'color' and methods li

Q4. How does garbage collection work in Java?
Ans. 
Garbage collection in Java automatically manages memory by reclaiming unused objects.
• Garbage collection identifies and removes objects that are no longer reachable by the program.

• It helps prevent memory leaks and allows developers to focus on writing code rather than managing memory.

• Java uses different garbage collection algorithms like Serial, Parallel, CMS, and G1.

• Developers can also manually trigger garbage collecti

Q5. What is the difference between checked and unchecked exceptions in Java?
Ans. 
Checked exceptions are checked at compile time, while unchecked exceptions are not.
• Checked exceptions must be either caught or declared in the method signature using 'throws' keyword.

• Unchecked exceptions do not need to be caught or declared.

• Examples of checked exceptions include IOException, ClassNotFoundException. Examples of unchecked exceptions include NullPointerException, ArrayIndexOutOfBoundsException.

Q2. What is a bandpass filter?
Ans. 
A bandpass filter is a type of electronic filter that allows signals within a certain frequency range to pass through while attenuating signals outside of that range.
• Bandpass filters are used to selectively filter out unwanted frequencies in electronic circuits.

• They have a lower cutoff frequency and an upper cutoff frequency that define the range of frequencies that can pass through.

• Examples of bandpass filters include...read more

Q3. What is the cutoff frequency?
Ans. 
Cutoff frequency is the frequency at which the output power is half of the maximum power.
• Cutoff frequency is commonly used in signal processing and filter design.

• It is the frequency at which the output power drops to half (-3 dB) of the maximum power.

• In low-pass filters, cutoff frequency is the frequency at which the output signal is attenuated by 3 dB.

• In high-pass filters, cutoff frequency is the frequency at which th

Q4. What is the difference between 32-bit and 64-bit operating systems?
Ans. 
32-bit operating systems can only utilize up to 4GB of RAM, while 64-bit operating systems can handle much larger amounts of RAM.
• 32-bit operating systems can only address up to 4GB of RAM, limiting the amount of memory that can be used by the system and applications.

• 64-bit operating systems can handle larger amounts of RAM, allowing for better performance and the ability to run more demanding applications.

• 64-bit operat...read more
