- Q3. What are some advantages of using Object-Oriented Programming (OOP)?
- Ans.
Advantages of OOP include code reusability, modularity, and easier maintenance.
Code reusability: Objects can be reused in different parts of the program, reducing redundancy.
Modularity: OOP allows for breaking down complex problems into smaller, more manageable parts.
Easier maintenance: Changes to one part of the codebase do not necessarily affect other parts, making maintenance easier.
Encapsulation: Data hiding and ab...
- Q4. What are access specifiers and what is their significance in Object-Oriented Programming?
- Ans.
Access specifiers define the level of access to class members in Object-Oriented Programming.
Access specifiers include public, private, protected, and default

Private members are only accessible within the class
Protected members are accessible within the class and its subclasses
Default access is when no access specifier is specified

- Q1. Implement queue with the help of two stacks
- Ans.
Queue can be implemented using two stacks by maintaining the order of elements in the stacks.
Create two stacks, let's call them stack1 and stack2
When an element is enqueued, push it to stack1
When an element is dequeued, pop all elements from stack1 and push them to stack2
Pop the top element from stack2 and return it as the dequeued element
If stack2 is empty, repeat step 3
To get the front element of the queue, peek the

- Q3. What is left join. Give example. And Full outer join?
- Ans.
Left join returns all records from left table and matching records from right table. Full outer join returns all records from both tables.
Left join is used to combine two tables based on a common column.
In left join, all records from the left table are returned along with matching records from the right table.
If there is no match in the right table, NULL values are returned.
Example: SELECT * FROM table1 LEFT JOIN table...
- Q4. What is magic functions and autoloading in PHP?
- Ans.
Magic functions are special methods in PHP that start with __. Autoloading is a way to automatically load classes.
Magic functions are used to handle certain events in PHP, such as object creation or property access.
Autoloading allows PHP to automatically load classes when they are needed, without requiring manual includes.
Magic functions can be used in conjunction with autoloading to dynamically load classes or handle
- Q5. Given three arrays sorted in non-decreasing order, print all common elements in these arrays. Examples: ar1[] = {1, 5, 10, 20, 40, 80} ar2[] = {6, 7, 20, 80, 100} ar3[] = {3, 4, 15, 20, 30, 70, 80, 120} Ou...
- Ans.
Given three sorted arrays, find common elements.
Create three pointers to traverse each array
Compare the elements at the pointers and move the pointer of the smallest element
If all pointers point to the same element, add it to the result and move all pointers

- Q6. A puzzle. You will be given with a 3 Litre container & a 7 Litre Container. Measure exactly 5 Litres of water
- Q7. Asked about one of my projects I mentioned in my resume?
- Q8. Find if a number is a power of 2 or not?
- Ans.
Check if a number is a power of 2 or not.
A power of 2 has only one bit set in its binary representation.
Use bitwise AND operator to check if the number is a power of 2.
If n is a power of 2, then n & (n-1) will be 0.

- Q1. What is event bubbling?
- Ans.
Event bubbling is the propagation of an event from the innermost child element to the outermost parent element.
Events triggered on a child element will also trigger on its parent elements
The event travels up the DOM tree until it reaches the document object
Can be stopped using event.stopPropagation()
Can be useful for event delegation
- Q2. Difference between .on(‘click’,function() and .click(function())
- Ans.
The .on('click',function() is a more flexible method than .click(function())
The .on() method can handle multiple events and selectors
The .click() method can only handle one event and one selector
The .on() method can also handle dynamically added elements
The .click() method cannot handle dynamically added elements

- Q7. By tossing a coin we can get either head or tail, i have a function toss() which return head or tail with equal probability
- Q8. You have to write a function for dice which will return number from 1-6 with equal probability. constraints : you can not use random function, you can use only toss function
- Ans.
Function to simulate dice roll with equal probability without using random function
Use a toss function that returns either 0 or 1 with equal probability
Call the toss function 3 times and convert the result to a binary number
If the binary number is greater than 0 and less than or equal to 6, return it
If the binary number is greater than 6, repeat the process
- Q9. Write a query to fetch duplicate email from table?
- Ans.
Query to fetch duplicate email from table
Use GROUP BY and HAVING clause to filter out duplicates
