We have a list of tasks. Each task can depend on other tasks.If task A depends on task B, then B should run before A. Implement the method getTaskWithDependencies such that it returns a list of task names in the correct order. Example:If we want to execute task “application A”, the method should return: The…

CoderPad provides a basic SQL sandbox with the following schema.You can also use commands like show tables and desc … Group employees_projects by employee_id and filter with HAVING COUNT(DISTINCT project_id) > 1. Use DISTINCT to guard against duplicate links; join employees only if names are needed. Add indexes on employee_id/project_id (or a composite) for performance….

Robinhood is famous for its referral program. It’s exciting to see users spreading the word across their friends and family. One thing that is interesting about the program is the network effect it creates. We would like to build a dashboard to track the status of the program. Specifically, we would like to learn about…

Core components Key APIs Data model (simplified) Scheduling strategy Failure & SLA handling Scaling The VOprep team has long accompanied candidates through various major…

Input (stdin)An order message is a request to trade shares: New fields: Order rules ✅ Output (stdout) After receiving an order at time T, emit prints: Following constraints: ✅ Example Output Explanation: ✅ Summary This problem simulates an execution algorithm constrained by: ✅ Trailing-minute external traded volume✅ Participation rate limits (PR)✅ Expiration of orders✅ Partial…

Input (stdin)The program reads the input line by line. Each line must be one of the following message types: • A print represents a trade that took place on the exchange: • A volume check is a request to report the total traded quantities of a security in the preceding minute, as well as its…

You have been tasked with creating an exchange where traders can buy and sell Sea Shells. The program reads incoming orders and emits trades. Input (stdin) – the input is a stream of limit orders. Each line is a separate order identified by its line number (starting at 1), with space-delimited fields: Examples: Processing orders…

A Kac ring is a dynamical system defined as follows: Part 1: Implement a Kac ring with the following interface: Brief summary: Simulate a circular system where balls move one step each tick and flip color only when leaving a marked slot. Build an object with step() and an O(1) color() that returns (white−black)/N(white –…

The program reads the input line by line from stdin.Each line is exactly one of the following message types: Fields (space-delimited): An order is: Output For each volume-check for security S at time T, emit exactly one line: Where: A volume-check response must be printed immediately before reading the next input line. For each order…

Ski season is approaching! You work at a ski resort and must ensure the slopes are fully covered with snow. You have a slope with indices from 0…N, and a collection of snow-making machines installed along the slope.Each machine is a tuple (index, range) meaning the machine sits at index and can cover the slope…
