(9 Questions)
- Q1. Write a go code to remove duplicate elements from a slice.
- Ans.
Go code to remove duplicate elements from a slice of strings
Use a map to keep track of unique elements
Iterate over the slice and add elements to the map
Create a new slice with unique elements from the map
- Q2. Difference between array and slice in Go.
- Ans.
Arrays have fixed length, slices are dynamic and can grow/shrink. Slices are references to arrays.
Arrays have fixed length, specified at compile time.
Slices are dynamic, can grow or shrink at runtime.
Slices are references to arrays, allowing for more flexibility.
Example: var arr [3]string // array with fixed length of 3
Example: slice := make([]string, 0) // slice with dynamic length
- Q3. Explain struct and interface
- Ans.
Struct is a user-defined data type that groups related data fields together. Interface defines a set of methods that a type must implement.
Struct is used to create complex data structures by grouping related data fields together.
Interface defines a set of methods that a type must implement. It allows for polymorphism in Go.
Example: type Person struct { Name string; Age int }
Example: type Shape interface { Area() float6...
- Q4. What is containerization.
- Ans.
Containerization is a method of packaging, distributing, and running applications in isolated environments called containers.
Containers are lightweight, portable, and can run on any platform that supports containerization.
They include everything needed to run the application, such as code, runtime, system tools, libraries, and settings.
Popular containerization tools include Docker, Kubernetes, and Podman.
Containerizati...
- Q5. Write a go code to implement struct.
- Ans.
Implementing a struct in Go code
Define a struct using the 'type' keyword
Add fields to the struct with their respective data types
Access struct fields using dot notation
- Q6. Explain goroutine.
- Ans.
Goroutine is a lightweight thread managed by Go runtime, allowing concurrent execution of functions.
Goroutines are created using the 'go' keyword in Go programming language.
They are more lightweight than threads and are managed by the Go runtime.
Goroutines allow for concurrent execution of functions without the need for manual thread management.
Example: go myFunction()
Example: go func() { // code here }
- Q7. How do you achieve concurrency in Go?
- Ans.
Concurrency in Go is achieved using goroutines and channels.
Use goroutines to run functions concurrently
Communicate between goroutines using channels
Avoid using shared memory for synchronization
- Q8. What is channel in Go? What are the differences between buffered and unbuffered channel?
- Ans.
A channel in Go is a communication mechanism that allows goroutines to communicate with each other.
Buffered channels have a specific capacity and can send multiple values without the need for a corresponding receive operation immediately.
Unbuffered channels have no capacity and require both a send and receive operation to be ready at the same time for communication to occur.
- Q9. What is scaling? Horizontal and vertical scaling.
- Ans.
Scaling refers to the ability of a system to handle increasing amounts of work or its potential to accommodate growth.
Horizontal scaling involves adding more machines to distribute the load, while vertical scaling involves increasing the resources of a single machine.
Horizontal scaling is more cost-effective and provides better fault tolerance, but can be more complex to implement.
Vertical scaling is simpler to impleme...

- Q1. Explain about stacks
- Ans.
Stacks are a data structure that follows the Last In First Out (LIFO) principle.
Elements are added and removed from the top of the stack
Common operations include push (add element) and pop (remove element)
Stacks can be implemented using arrays or linked lists
Examples of stack usage include function call stack and undo/redo functionality in text editors
- Q2. To find middle number in the linked list
- Ans.
To find the middle number in a linked list.
Traverse the linked list using two pointers, one moving twice as fast as the other.
When the fast pointer reaches the end, the slow pointer will be at the middle node.
If the linked list has even number of nodes, there will be two middle nodes. Return either one.

- Q1. There's a string s1,s2 and s3. s1 and s2 are divided into n and m parts respectively. check if, after interleaving strings s1 and s2, we get s3 as one of the answers.
- Ans.
Check if after interleaving strings s1 and s2, we get s3 as one of the answers.
Create a recursive function to check all possible interleavings of s1 and s2
Check if the current interleaving matches s3
Return true if a valid interleaving is found, false otherwise
- Q2. Difference between cluster and non-cluster indexing. Do you know about database indexing?
- Ans.
Cluster indexing physically reorders the data on disk to match the index, while non-cluster indexing does not.
Cluster indexing physically reorders the data on disk to match the index structure, leading to faster retrieval of data.
Non-cluster indexing creates a separate data structure that points to the actual data, which may result in slower retrieval times.
Cluster indexing is typically used in primary keys, while non-...
- Q3. Difference between stack and heap memory.
- Ans.
Stack memory is used for static memory allocation and follows a Last In First Out (LIFO) structure, while heap memory is used for dynamic memory allocation and has a more flexible structure.
Stack memory is limited in size and is typically faster to access compared to heap memory.
Variables stored in stack memory have a fixed size determined at compile time, while variables in heap memory can have a size determined at ru...
- Q4. What is a stable sort?
- Ans.
A stable sort is a sorting algorithm that preserves the relative order of equal elements in the sorted output.
Stable sorts are useful when the original order of equal elements needs to be maintained.
Examples of stable sorting algorithms include Merge Sort, Bubble Sort, and Insertion Sort.
In a stable sort, if two elements have the same key value, their relative order in the original array is preserved in the sorted arra
- Q5. What's the time complexity of insertion in a hashmap?
- Ans.
Time complexity of insertion in a hashmap is O(1).
Insertion in a hashmap has a constant time complexity of O(1) on average.
This is because hashmaps use a hashing function to determine the index where the key-value pair should be stored.
Even in the worst-case scenario, where there are collisions, the time complexity is still O(1) due to techniques like chaining or open addressing.
Example: Inserting a key-value pair into...
- Q6. What is hashing?
- Ans.
Hashing is a process of converting input data into a fixed-size string of bytes using a hash function.
Hashing is used to securely store passwords by converting them into a hash value.
Hashing is used in data structures like hash tables to quickly retrieve data based on a key.
Common hash functions include MD5, SHA-1, and SHA-256.
