Q1. 
Intersection of Two Unsorted Arrays Problem Statement
Given two integer arrays ARR1 and ARR2 of sizes 'N' and 'M' respectively, find the intersection of these arrays. The intersection is defined as the se...read more
Ans. 
Find the intersection of two unsorted arrays while maintaining the order of elements from the first array.
• Iterate through the elements of the first array and check if they exist in the second array.

• Use a hash set to keep track of elements already seen in the second array for efficient lookup.

• Maintain the order of elements from the first array while finding the intersection.

• Handle duplicate elements in both arrays appro...read more

Ans. 
Find the length of the longest substring without repeating characters in a given string.
• Use a sliding window approach to keep track of the longest substring without repeating characters.

• Use a hashmap to store the index of each character in the string.

• Update the start index of the window when a repeating character is encountered.

• Calculate the maximum length of the substring as you iterate through the string.

Ans. 
Search for an element in a rotated sorted array efficiently in O(logN) time complexity.
• Implement binary search to find the pivot point where rotation occurs.

• Divide the array into two subarrays and perform binary search on the appropriate subarray.

• Handle cases where the element may be in the left or right subarray after rotation.

• Return the index of the element if found, else return -1.

Q4. What is the difference between abstraction and inheritance?
Ans. 
Abstraction is hiding the implementation details while inheritance is a mechanism for creating new classes using existing classes.
• Abstraction focuses on hiding the internal implementation details of a class, allowing the user to only interact with the necessary information.

• Inheritance allows a class to inherit properties and behavior from another class, promoting code reusability and creating a hierarchy of classes.

• Abs...read more

Q1. What is event bubbling in JavaScript?
Ans. 
Event bubbling is the process where an event triggered on a child element is propagated up through its parent elements.
• In event bubbling, when an event occurs on a child element, it first runs the event handlers on the child element, then on its parent, then all the way up to the top level of the DOM.

• Event bubbling allows for delegation of event handling to a parent element, reducing the number of event listeners neede...read more
