I prioritize features using a combination of customer feedback, business impact, and technical feasibility.
Gather customer feedback through surveys and interviews to understand their needs.
Use the RICE scoring model (Reach, Impact, Confidence, Effort) to evaluate features.
Align features with business goals, such as increasing revenue or improving user retention.
Consider technical feasibility and resource availabil...
Identify and remove duplicates from an array of strings efficiently.
Use a Set to store unique strings. Example: ['apple', 'banana', 'apple'] becomes ['apple', 'banana'].
Iterate through the array and add each string to the Set. Duplicates are automatically ignored.
Convert the Set back to an array if needed. Example: Set(['apple', 'banana']) to ['apple', 'banana'].
Consider using built-in functions like filter() or r...
Identify and extract all palindromic substrings from a given string.
A palindrome reads the same forwards and backwards. Example: 'racecar'.
Iterate through each substring of the string and check if it's a palindrome.
Use two pointers to compare characters from both ends towards the center.
Consider edge cases like single characters and empty strings.
Example input: 'madam arora teaches malayalam' -> Output: ['madam...
Reversing a linked list involves changing the direction of its pointers to reverse the order of nodes.
1. Initialize three pointers: prev (null), current (head), and next (null).
2. Iterate through the list: while current is not null, do the following:
- Store the next node: next = current.next.
- Reverse the current node's pointer: current.next = prev.
- Move prev and current one step forward: prev = current;...
Optimizing code involves improving efficiency while reducing time and space complexity.
Use efficient algorithms: For example, use QuickSort instead of BubbleSort for sorting arrays.
Reduce space complexity: Use in-place algorithms like Merge Sort to save memory.
Avoid unnecessary computations: Cache results of expensive function calls (memoization).
Choose appropriate data structures: Use HashMaps for quick lookups i...
Debounce function delays the execution of a function until after a specified amount of time has passed since the last time it was invoked.
Create a function that takes a function and a delay time as parameters
Use setTimeout to delay the execution of the function
Use clearTimeout to reset the timer if the function is invoked again within the delay time
The question is asking to calculate the number of hops an elevator needs to travel between floors.
Calculate the difference between the starting floor and the destination floor
Divide the difference by the maximum number of floors the elevator can travel in one hop
Round up the result to get the number of hops needed
An online real time document sharing tool for collaboration and communication

Software development life cycle is a process used by software development teams to design, develop, test, and deploy software.
It involves planning, designing, coding, testing, and deployment stages.
Each stage has specific goals and deliverables.
Examples of SDLC models include Waterfall, Agile, and DevOps.
Find all triplets in an array of integers without duplicates
Iterate through the array and for each element, find all pairs that sum up to the negative of that element
Use a set to store the seen elements to avoid duplicates
Time complexity can be improved to O(n^2) by sorting the array first
The immediate higher number to the right of each element in an array
Iterate through the array from right to left
For each element, compare it with the elements to its right to find the immediate higher number
Store the immediate higher number in a new array
Count pairs in an array whose sum is a perfect square.
Iterate through the array and calculate the sum of each pair.
Check if the sum is a perfect square using a function.
Increment a counter if the sum is a perfect square.
Return the final count of pairs.
Design a parking lot system to manage parking spaces, vehicles, and payment processing.
Define classes: ParkingLot, ParkingSpace, Vehicle, and Payment.
ParkingLot should manage multiple ParkingSpaces and track available spots.
ParkingSpace can be of different types: Compact, Regular, and Handicapped.
Vehicle class can include attributes like license plate, size, and type.
Implement methods for parking, retrieving vehicles, ...
To find the Kth largest number in a Binary Search Tree (BST), we can perform an in-order traversal and keep track of the Kth largest element.
Perform an in-order traversal of the BST to get the elements in non-decreasing order.
Keep track of the Kth largest element while traversing the BST.
Return the Kth largest element once found.

Transactions in Spring Boot manage database transactions in a declarative way.
Spring Boot uses @Transactional annotation to mark a method as transactional.
Transactions can be managed at class level or method level.
Rollback can be configured based on specific exceptions.
Example: @Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)
Check if a given string is a palindrome
Iterate through the string from both ends and compare characters
Ignore spaces and punctuation marks while checking for palindrome
Convert the string to lowercase for case-insensitive comparison
