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 an Autocomplete Service Let's design an autocomplete service, similar to what you'd find in Google Search or a code editor. The service should provide suggestions as the user types a query. Consider the following requirements: Functionality: The service should return the top k most relevant suggestions based on the user's input. Suggestions should be ranked by popularity (e.g., frequency of search). The system should support a large number of concurrent users. The system should be able to handle a large vocabulary of terms. The service needs to provide real-time or near real-time suggestions (low latency). The service should be fault-tolerant and highly available. Example: If a user types softw, the service might return: [software engineer, software developer, software company, software jobs]. If a user types ja, the service might return: [java, javascript, jakarta, james]. Considerations: How would you store the data to enable fast lookups? How would you handle updates to the suggestion data (e.g., new terms, updated popularity)? How would you scale the system to handle a large number of requests? What algorithms and data structures would you use? How would you optimize for latency? How would you handle different languages or character sets? How would you measure the performance of the service? Walk me through the design of this autocomplete service, considering the key components, data structures, algorithms, and scaling strategies. Describe any trade-offs you would make.

Tell me about a time you had a conflict with a colleague. What was the nature of the conflict, and how did you approach resolving it? What was the outcome, and what did you learn from the experience? For example, perhaps you disagreed on the best approach to a technical problem, or maybe there was a misunderstanding about responsibilities. How did you communicate your perspective, and how did you listen to theirs? What steps did you take to find a mutually agreeable solution? Did you involve a mediator or supervisor, or were you able to resolve it yourselves? What were the key takeaways from that situation, and how have you applied those lessons to future collaborations? It is important to show that you can handle conflict well.
