Given an array of integers where each element represents the maximum jump length at that position, determine if you can reach the last index from the starting index (index 0). Return true if reachable, false otherwise. For example, `[2,3,1,1,4]` should return true, and `[3,2,1,0,4]` should return false as you cannot proceed past index 3 in the second example. The array length will be between 1 and 10,000, with element values between 0 and 100,000 inclusive.

Data Structures & AlgorithmsMedium

You are given an integer array nums of length n. You are initially positioned at nums[0]. Each element nums[i] represents the maximum length of a forward jump from position i. In other words, if you are at nums[i], you can jump to any nums[i + j] where: 0 <= j <= nums[i] and i + j < n Return true if you can reach nums[n - 1], or false otherwise. Example 1: Input: nums = [2,3,1,1,4] Output: true Explanation: Jump 1 step from index 0 to 1, then 3 steps to the last index. Example 2: Input: nums = [3,2,1,0,4] Output: false Explanation: You will always arrive at index 3 no matter what. Its maximum jump length is 0, which makes it impossible to reach the last index. Constraints: 1 <= nums.length <= 10^4 0 <= nums[i] <= 10^5

Design a database schema for a library, including tables, columns, keys, and relationships.

System DesignHard

Let's design a database for a library. Consider the following requirements: Books: The library has a collection of books. Each book has a title, an author (or authors), a publication year, an ISBN, and a genre. A book can have multiple authors. Members: The library has members who can borrow books. Each member has a unique member ID, a name, an address, and a phone number. Borrowing: The library needs to keep track of which books are borrowed by which members and when they are borrowed and returned. A member can borrow multiple books, and a book can be borrowed by multiple members over time. Reservations: Members can reserve books that are currently checked out. The system needs to keep track of reservations and their order. Late Fees: The library charges late fees for overdue books. The system needs to calculate and track these fees. Based on these requirements, design a relational database schema. Include the tables, columns, data types, primary keys, and foreign keys. Provide a brief explanation for each table and the relationships between them. How would you handle the many-to-many relationship between books and authors? How would you handle the many-to-many relationship between members and borrowed books? How would you ensure data integrity, such as preventing a member from borrowing the same book twice at the same time?

Tell me about a time you disagreed with a manager.

Behavioral

Tell me about a time you disagreed with a manager. What was the situation, and how did you handle it? What was the outcome, and what did you learn from the experience? For example, perhaps you had a disagreement about project priorities, a technical approach, or a team management style. It could be a situation where you felt strongly about a different course of action and had to navigate the disagreement professionally. Describe the specific steps you took to communicate your perspective, understand your manager's viewpoint, and reach a resolution. What factors did you consider in deciding how to approach the situation, and what alternative approaches did you consider? How did you ensure that the disagreement didn't negatively impact your working relationship or the overall team dynamic? What would you do differently in a similar situation in the future?
