Zoho Software Developer Interview Questions and Answers
37 Interview questions
Arrays and linked lists are commonly used data structures in my preferred programming languages.
Arrays are used for storing a collection of elements of the same data type in contiguous memory locations.
Linked lists are used for storing elements in nodes with pointers to the next node, allowing for dynamic memory allocation.
Examples: int[] array = new int[5]; LinkedList<String> list = new LinkedList<>()...
Find the next greater element in an array
Iterate through the array and use a stack to keep track of elements
For each element, pop elements from the stack until finding a greater element
Store the next greater element in a result array
Arrays are efficient for structured data due to constant time access and insertion at specific indexes.
Arrays provide constant time access to elements at specific indexes.
Insertion and deletion at specific indexes in arrays are also efficient.
Examples of structured data that can be efficiently stored in arrays include lists, queues, and stacks.
Polymorphism in OOP allows objects of different classes to be treated as objects of a common superclass.
Polymorphism allows for flexibility and reusability in code.
It enables a single interface to be used for different data types.
Examples include method overloading and method overriding.
Generate all possible permutations of open and closing braces
Use recursion to generate all possible combinations of open and closing braces
Keep track of the number of open and closing braces used in each combination
Terminate recursion when the number of open and closing braces reaches the desired length
The default access modifier for interfaces in C# is 'public'.
Interfaces in C# are by default public and cannot have any other access modifier.
Explicitly specifying 'public' for an interface is redundant.
Example: public interface IExampleInterface { }
Function overloading is having multiple functions with the same name but different parameters, while function overriding is redefining a function in a subclass with the same name and parameters as in the superclass.
Function overloading is done within the same class, while function overriding is done in a subclass.
Function overloading is resolved at compile time based on the number and type of arguments, while func...
Design a ticketing system for taxis using OOP principles to manage bookings, vehicles, and users efficiently.
Define classes: Ticket, Taxi, User, and Booking.
Use inheritance for different types of taxis (e.g., Sedan, SUV).
Implement methods for booking a taxi, canceling a booking, and viewing available taxis.
Utilize encapsulation to protect sensitive data (e.g., user information).

Object-Oriented Programming (OOP) is a programming paradigm based on the concept of objects, which can contain data and code.
Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).
Inheritance: Mechanism to create a new class using properties and methods of an existing class (e.g., a 'Dog' class inheriting from an 'Animal' class).
Polymorphism: Ability to present the same i...

- Q1. Difference between hashmap and hasptable
- Ans.
HashMap and Hashtable are both data structures that store key-value pairs, but they differ in synchronization and performance.
HashMap is not synchronized, making it faster but not thread-safe. Example: HashMap<String, Integer> map = new HashMap<>();
Hashtable is synchronized, making it thread-safe but slower. Example: Hashtable<String, Integer> table = new Hashtable<>();
HashMap allows null keys a...
- Q2. Why typescript over javascript
- Ans.
TypeScript enhances JavaScript with static typing, better tooling, and improved maintainability for large applications.
Static Typing: TypeScript allows developers to define types, reducing runtime errors. Example: `let num: number = 5;`
Enhanced Tooling: TypeScript provides better IDE support with features like autocompletion and refactoring tools.
Improved Readability: Type annotations make the code more understandable,...
- Q3. Find the percentage of increace in the quantity of item after making it price 20% extra
- Ans.
Calculate the percentage increase in item quantity when its price is raised by 20%.
When the price increases, demand may decrease, affecting quantity sold.
If price rises by 20%, consumers may buy less, leading to a potential decrease in quantity.
Example: If an item costs $100 and is increased to $120, consumers may buy fewer units.
The actual percentage change in quantity depends on price elasticity of demand.
- Q4. What is normalization
- Q5. Date and time api available
- Ans.
Various APIs exist for handling date and time, including JavaScript's Date, Python's datetime, and Java's LocalDateTime.
JavaScript: Use the Date object for current date/time: `new Date()`.
Python: The datetime module allows for date manipulation: `from datetime import datetime`.
Java: LocalDateTime class in java.time package for date/time without timezone: `LocalDateTime.now()`.
REST APIs: Many web services provide endpoi...
