Q1. What is ticketing tool? Describe that??
A ticketing tool is a software used to manage and track customer support requests or incidents.
It allows users to submit tickets or requests for assistance.
It assigns tickets to appropriate support staff for resolution.
It tracks the status and progress of each ticket until it is resolved.
It provides reporting and analytics on ticket volume, resolution time, and customer satisfaction.
Examples include ServiceNow, JIRA Service Desk, and Zendesk.
Q2. What is subnet?? What is subnet of 120?
A subnet is a smaller network within a larger network. The subnet of 120 depends on the subnet mask.
Subnet is a way to divide a larger network into smaller ones
Subnet mask determines the size of the subnet
Subnetting helps in efficient use of IP addresses
The subnet of 120 depends on the subnet mask used
Q3. Explain activity lifecycle
Activity lifecycle refers to the series of states an activity goes through during its lifetime in an Android app.
onCreate() - activity is created
onStart() - activity becomes visible to the user
onResume() - activity is interacting with the user
onPause() - activity is partially visible but still running
onStop() - activity is no longer visible to the user
onDestroy() - activity is being destroyed
Q4. MVVM Architecture explain
MVVM is an architectural pattern used in software development, particularly in Android apps, to separate the user interface from the business logic.
MVVM stands for Model-View-ViewModel
Model represents the data and business logic
View is the UI component that displays the data and interacts with the user
ViewModel acts as a mediator between the Model and the View, handling user interactions and updating the Model
MVVM helps in separating concerns, making code more modular and eas...read more
Q5. What is DHCP,DNS?
DHCP is a protocol that assigns IP addresses to devices on a network. DNS is a system that translates domain names to IP addresses.
DHCP stands for Dynamic Host Configuration Protocol
DHCP assigns IP addresses to devices on a network
DNS stands for Domain Name System
DNS translates domain names to IP addresses
DNS is used to access websites and other resources on the internet
Q6. Difference between Domain and workgroup???
Domain is a centralized network where computers are managed by a server, while workgroup is a decentralized network where computers are managed individually.
Domain is managed by a domain controller server, while workgroup has no centralized server.
Domain allows for centralized management of user accounts, security policies, and resources, while workgroup does not.
Domain allows for easier scalability and security, while workgroup is more suitable for small networks with fewer ...read more
Q7. 1. Check all the permutations of palindrome in an array
Find all permutations of palindromes in an array of strings.
Iterate through each string in the array.
For each string, generate all possible permutations.
Check if each permutation is a palindrome.
Return the list of palindromic permutations.
Q8. Write the code for even number
Code to identify even numbers
Use the modulo operator (%) to check if a number is divisible by 2
If the remainder is 0, then the number is even
Example: int num = 6; if(num % 2 == 0) { // num is even }
Q9. 3. Swap numbers using bit operators
Swapping numbers using bit operators.
Use XOR operator to swap two numbers without using a temporary variable
XORing a number with itself results in 0
Example: a = 5, b = 7. a ^= b; b ^= a; a ^= b; // a = 7, b = 5
Q10. Print the various star patterns
Various star patterns can be printed using loops and nested loops in Python.
Use nested loops to print different patterns of stars.
Patterns can include right triangle, left triangle, diamond, square, etc.
Adjust the number of rows and columns in the loops to create different patterns.
Q11. 2. Toggle a bit
Toggle a bit in a binary number
Convert the number to binary representation
Identify the bit position to toggle
Toggle the bit using bitwise XOR operator
Convert the modified binary number back to decimal
Q12. what are access modifiers
Access modifiers are keywords in C++ that control the visibility and accessibility of class members.
Access modifiers include public, private, and protected.
Public members are accessible from outside the class.
Private members are only accessible within the class.
Protected members are accessible within the class and its subclasses.
Q13. 1. diff between acf pacf
ACF measures the linear relationship between an observation and its lagged values. PACF measures the direct relationship.
ACF (Autocorrelation Function) measures the correlation between an observation and its lagged values.
PACF (Partial Autocorrelation Function) measures the correlation between an observation and its lagged values, while removing the indirect effects of intermediate lags.
ACF is used to identify the order of an AutoRegressive (AR) model.
PACF is used to identify...read more
Q14. explain OOps in C++
Object-oriented programming in C++ involves using classes and objects to organize code and data for better reusability and modularity.
Classes are user-defined data types that encapsulate data and functions that operate on that data.
Objects are instances of classes that hold data and can call member functions.
Inheritance allows classes to inherit properties and behaviors from other classes.
Polymorphism enables objects to be treated as instances of their parent class.
Encapsulat...read more
