(6 Questions)
- Q1. Implementation of opps concepts in go
- Ans.
Go supports object-oriented programming principles through struct types and methods.
Go uses struct types to define objects with fields and methods.
Methods can be defined on struct types to provide behavior to objects.
Go does not have classes like traditional OOP languages, but it supports encapsulation, inheritance, and polymorphism through struct embedding and interfaces.
- Q2. Internal working of arrays and slices
- Ans.
Arrays are fixed-size collections of elements of the same type, while slices are dynamic arrays with a flexible size.
Arrays have a fixed size determined at compile time.
Slices are dynamic arrays that can grow or shrink.
Arrays and slices are both zero-indexed.
Arrays are passed by value, while slices are passed by reference.
Example: var arr [3]string = [3]string{"apple", "banana", "orange"}
Example: var slice []string = [
- Q3. Goroutines and their implementation
- Ans.
Goroutines are lightweight threads managed by Go runtime, allowing concurrent execution of functions.
Goroutines are created using the 'go' keyword followed by a function call.
They are multiplexed onto multiple OS threads by the Go runtime.
Goroutines communicate using channels to share data safely.
They are more efficient than traditional threads due to their lightweight nature.
- Q4. Some resume specific questions User authentication and authorization
- Q5. C++ vs go points
- Ans.
Go is simpler, more efficient, and easier to learn compared to C++.
Go has a simpler syntax and is easier to read and write compared to C++.
Go has built-in concurrency support with goroutines and channels, making it easier to write concurrent programs.
Go has a garbage collector, which simplifies memory management compared to manual memory management in C++.
Go compiles faster than C++ due to its simpler type system and l...
- Q6. How to process lacks of data efficiently.?
- Ans.
Efficiently process large amounts of data by using parallel processing, optimizing algorithms, and utilizing data structures.
Utilize parallel processing techniques such as goroutines in Golang to process data concurrently.
Optimize algorithms to reduce time complexity and improve processing speed.
Use efficient data structures like maps, slices, and channels to store and manipulate data.
Consider using caching mechanisms ...

- Q1. What are goroutines
- Ans.
Goroutines are lightweight threads of execution in Go.
Goroutines are functions that can run concurrently with other functions.
They are cheap to create and can be used to handle multiple tasks simultaneously.
They communicate with each other using channels.
Goroutines are managed by the Go runtime and can be scheduled on multiple processors.
Example: go func() { fmt.Println("Hello, world!") }()
Example: go func() { result :...

- Q2. Palindrome program in java
- Ans.
A palindrome program in Java checks if a given string reads the same forwards and backwards.
Create a function that takes a string input
Use a loop to compare characters from both ends of the string
Return true if the string is a palindrome, false otherwise
- Q3. Diamond problem in java
- Ans.
Diamond problem in Java occurs when a class inherits from two classes that have a common ancestor, resulting in ambiguity.
Diamond problem arises in multiple inheritance scenarios in Java.
It occurs when a class inherits from two classes that have a common ancestor.
To resolve the diamond problem, Java does not support multiple inheritance through classes, but it can be achieved using interfaces.
Example: Class A and Class...
