10+ Cloud Analogy Interview Questions and Answers for Freshers

Reverse a singly linked list of integers and return the head of the reversed linked list.

• Iterate through the linked list and reverse the pointers to point to the previous node.

• Keep track of the current, previous, and next nodes while reversing the linked list.

• Update the head of the reversed linked list as the last node encountered during reversal.

The task is to find the total number of subsequences in which all elements are equal in an integer array.

• Iterate through the array and count the frequency of each element.

• For each element, calculate the number of subsequences with all elements equal using the formula (frequency * (frequency - 1) / 2).

• Sum up the counts for all elements and return the result modulo 10^9 + 7.

Function to print star patterns based on the given number of rows 'N'.

• Iterate through each row from 1 to N

• For each row, print spaces (N-row) followed by stars (2*row-1)

• Repeat until all rows are printed

Calculate the sum of minimum and maximum elements of all subarrays of size K in an array.

• Iterate through the array and maintain a deque to store the indices of elements in the current window of size K.

• Keep track of the minimum and maximum elements in the current window and update the sum accordingly.

• Return the total sum of minimum and maximum elements for all subarrays of size K.

A program to find palindrome numbers in a given range.

• Iterate through the given range of numbers

• Convert each number to a string and check if it is equal to its reverse

• If yes, add it to the list of palindrome numbers

Carry is generated when the sum of two digits is greater than 9.

• Carry is a digit that is carried over to the next place value in the sum.

• For example, in the sum 56 + 78, the carry generated is 1 (5+7=12, carry 1, 6+8+1=15).

• Carry is important in addition of large numbers and in binary addition.

Code to reverse a string of your name

• Create a function that takes a string as input

• Use built-in functions like reverse() or loop through the string to reverse it

• Return the reversed string

Code to print pyramid pattern in Python

• Use nested loops to print spaces and stars in each row

• Increment the number of stars in each row to form the pyramid shape

• Example: for a pyramid with 5 rows, the code would look like this:

• for i in range(5):

• print(' '*(5-i-1) + '*'*(2*i+1))

Campaigns, Promotions, and Coupons are marketing strategies used to attract customers and increase sales.

• Campaigns are strategic marketing efforts to promote a product or service over a specific period of time.

• Coupons are vouchers that entitle the holder to a discount on a particular product or service.

• Examples: Black Friday campaign, Buy One Get One Free promotion...read more

Global JS refers to JavaScript variables or functions that are accessible from anywhere in the code.

• Global JS variables are declared outside of any function and can be accessed from any part of the code.

• Global JS functions are defined without being enclosed within another function and can be called from anywhere in the code.

• Using global variables or functions can lead to potential conflicts and security risks.

Black box testing is a software testing technique where the internal workings of the system are not known to the tester.

• Tests the functionality of the system without knowing the internal code

• Focuses on input and output of the system

• Tests for user interface, performance, and security

• Examples include acceptance testing and regression testing

Inheritance is a concept in object-oriented programming where a class can inherit attributes and methods from another class.

• Allows a class to inherit attributes and methods from another class

• Promotes code reusability and reduces redundancy

• Creates a parent-child relationship between classes

• Types of inheritance include single, multiple, multilevel, and hierarchical

• Example: Class 'Animal' can be a parent class with attributes like 'name' and methods like 'eat', while class 'Dog'...read more

Objects in OOPs refer to instances of classes that encapsulate data and behavior.

• Objects are created based on a class blueprint

• Objects have attributes (data) and methods (behavior)

• Objects allow for data encapsulation and abstraction

• Example: Class 'Car' can have objects like 'Toyota', 'Honda', etc.

A quality analyst is responsible for ensuring that products or services meet the required standards and specifications.

• Conducting quality assurance tests and inspections

• Analyzing data to identify areas for improvement

• Developing and implementing quality control procedures

• Collaborating with other departments to ensure quality standards are met

• Providing feedback to management on quality issues

• Examples: testing software for bugs, inspecting manufactured products for defects

Check if array of strings is a palindrome or not.

• Iterate through the array and compare each string with its reverse to check for palindrome.

• Ignore spaces and punctuation while checking for palindrome.

• Example: ['madam', 'racecar', 'hello', 'level'] should return true.

White box testing is a testing technique that involves testing the internal structure of the software.

• It is also known as clear box testing or structural testing.

• It requires knowledge of the code and the internal workings of the software.

• It is used to test the logic and flow of the code.

• Examples include unit testing and integration testing.

• It is usually performed by developers or testers with programming knowledge.
