Associate Software Development Engineer Interview Questions and Answers

Rearrange a binary array to move all 0s to the left and 1s to the right using a two-pointer approach.

• Use two pointers: one starting from the left (i) and one from the right (j).

• Iterate through the array until i is less than j.

• If arr[i] is 0, increment i. If arr[j] is 1, decrement j.

• If arr[i] is 1 and arr[j] is 0, swap them and adjust both pointers.

• Continue until all elements are sorted.

Remove duplicates from an array while maintaining the original order of elements.

• Use a set to track seen elements and a list to store the result.

• Iterate through the array, adding elements to the result if they haven't been seen.

• Example: For arr=[2,1,2,3,4,3,4,4], the output will be [2,1,3,4].

• This approach ensures O(n) time complexity, where n is the length of the array.

Explanation of OS, threading, paging, database transactions (ACID properties), and computer networks.

• OS (Operating System) is a software that manages computer hardware resources and provides services for computer programs.

• Threading involves the ability of a program to execute multiple parts concurrently.

• Paging is a memory management scheme that eliminates the need for contiguous allocation of physical memory.

• Database transactions follow ACID properties - Atomicity, Consistenc...read more

Object oriented programming is a programming paradigm based on the concept of objects, which can contain data and code.

• Objects: Instances of classes that encapsulate data and behavior

• Classes: Blueprints for creating objects with shared attributes and methods

• Inheritance: Ability for classes to inherit attributes and methods from other classes

• Polymorphism: Ability for objects to take on multiple forms or behaviors

• Encapsulation: Hiding the internal state of an object and requiri...read more

Schema is a structure that represents the organization of data in a database.

• Schema defines the tables, fields, relationships, and constraints in a database.

• It ensures data integrity and consistency by enforcing rules on the data.

• Examples of schema elements include tables, columns, primary keys, foreign keys, and indexes.

Merge sort is a divide and conquer algorithm that sorts an array by dividing it into two halves, sorting them separately, and then merging the sorted halves.

• Divide the array into two halves

• Sort each half recursively

• Merge the two sorted halves

• Time complexity is O(nlogn)

• Space complexity is O(n)
