This is a classic array problem that frequently appears in interviews, with tricky edge cases caused by negative numbers. The key challenge lies in handling sign changes that can flip maximum and minimum products. Interviewers use this question to evaluate a candidate’s reasoning process, adaptability, and ability to explain dynamic decision-making clearly during live interviews….

Question 1: String Replace Without Using Built-in Functions Question 2: LinkedIn Connection Distance These questions reflect LinkedIn’s focus on fundamental implementation skills and graph-based reasoning. The string replacement problem tests low-level string traversal and edge-case handling without relying on built-in helpers. The connection distance problem maps directly to shortest path search in an unweighted graph….

This problem tests a candidate’s ability to map phone keypad digits to letters and efficiently match words against a given dictionary. The key is avoiding brute-force generation and instead using reverse mapping or preprocessing strategies. Interviewers focus heavily on reasoning clarity, optimization choices, and time complexity discussion. In live interviews, explaining the approach clearly is…

I successfully received an offer from Nvidia (US), and I’d like to share my complete interview experience here. Hopefully, this can serve as a reference for those who are preparing for interviews at Nvidia or similar companies. The first round was a phone interview with the hiring manager. This round mainly focused on my background…

This problem asks you to design a simplified package manager similar to Homebrew or APT. At its core, it tests your ability to:

Build a 3×3 grid of light cells (omitting the center cell),where you can click on the cells to activate them (turn green). When all the cells have been activated,they will be deactivated one-by-one in the reverse order they were activated,with a 300ms interval in between. A practical UI problem involving event ordering, async timing, and…

Problem Description (Original) 1. Problem You are given a simple web page layout with a navigation menu: The page initially loads only the basic structure. 2. Solution / Requirement Implement lazy loading, where content is loaded only when needed, instead of loading everything at page initialization. You are also required to add content dynamically to…

Problem Description You are given a sorted list of distinct integers ranging from 0 to 99. For example: Your task is to produce a string that describes the numbers missing from the list. In this example, the missing numbers are: Examples This problem asks you to scan a sorted list of integers and generate a…

Problem Description There are a total of numCourses courses you have to take, labeled from 0 to numCourses – 1. You are given an array prerequisites where prerequisites[i] = [ai, bi] indicates that you must take course bi first if you want to take course ai. For example, the pair [0, 1] indicates that to…
