Associate Software Engineering Intern Interview Questions and Answers

Program to check if 2 words are anagrams and to print a sentence with reverse order of words.

• Create a function to check if two words are anagrams by sorting the characters in each word and comparing them.

• Create a function to reverse the order of words in a sentence by splitting the sentence into words, reversing the order, and joining them back together.

• Use arrays of strings to store the words in the sentence and the two words to check for anagrams.

Selection sort and insertion sort programs for array of strings

• Selection sort: Find the smallest element in the array and swap it with the first element, repeat for remaining elements

• Insertion sort: Iterate through the array, for each element, compare with previous elements and insert in correct position

Abstraction and polymorphism are key concepts in object-oriented programming.

• Abstraction involves hiding the implementation details and showing only the necessary features of an object.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• Example of abstraction: defining a Shape class with methods like calculateArea() without specifying how each shape calculates its area.

• Example of polymorphism: having a superclass Animal with a meth...read more

Print all 8 digit numbers whose reverse and 1/4th is the same.

• Iterate through all 8 digit numbers and check if reverse is equal to 1/4th of the number.

• Example: 12345678 -> reverse is 87654321, 1/4th is 3086421, not equal.

• Example: 12344321 -> reverse is 12344321, 1/4th is 3086080, equal.

Create a simple login page in HTML

• Use <form> element to create a form for login

• Include <input> elements for username and password

• Add a <button> element for submitting the form

• Use CSS for styling the login page

In JavaScript, & is a bitwise AND operator while && is a logical AND operator.

• Use & for bitwise operations on individual bits of two numbers.

• Use && for logical operations to check if both conditions are true.

• Example: 5 & 3 returns 1 (0101 & 0011 = 0001)

• Example: true && false returns false

Async await in JavaScript allows for asynchronous programming in a more readable and synchronous-like manner.

• Async functions return a Promise.

• Await can only be used inside an async function.

• Async await simplifies handling asynchronous operations compared to using callbacks or Promises.

• Example: async function fetchData() { await fetch('https://api.example.com/data'); }

Count Inversion problem

• Count the number of inversions in an array

• An inversion occurs when two elements in the array are out of order

• Use a divide and conquer approach to solve the problem efficiently

• Merge sort algorithm can be used to count inversions
