Round 3 : Coding 2

1. https://leetcode.com/problems/top-k-frequent-elements/description/

// Given an input string s and a pattern p, implement regular expression matching with support for \'.\' and \'*\' where:  
  
// - . Matches any single character.\u200B\u200B\u200B\u200B  
// - * Matches zero or more of the preceding element.  
  
// The matching should cover the entire input string (not partial).  
  
// Example 1:  
  
// Input: s = "aa", p = "a"  
// Output: false  
// Explanation: "a" does not match the entire string "aa".  
  
// Example 2:  
  
// Input: s = "aa", p = "a*"  
// Output: true  
// Explanation: \'*\' means zero or more of the preceding element, \'a\'. Therefore, by repeating \'a\' once, it becomes "aa".  
  
// Example 3:  
  
// Input: s = "ab", p = ".*"  
// Output: true  
// Explanation: ".*" means "zero or more (*) of any character (.)".  
  
// Constraints:  
  
// - 1 <= s.length <= 20  
// - 1 <= p.length <= 20  
// - s contains only lowercase English letters.  
// - p contains only lowercase English letters, \'.\', and \'*\'.  
// - It is guaranteed for each appearance of the character \'*\', there will be a previous valid character to match.  

**Round 4 : Product **

Product manager asking product and general questions. DIscussion on style of work

Round 5 : System Design

MVC model, API Design, Database Design

  
  
// Suppose you have a database schema with three tables: Employees, Departments, and Salaries.  
//  The Employees table stores information about employees, including their EmployeeID, Name, and DepartmentID.  
//   The Departments table contains information about different departments in the company, including their DepartmentID and DepartmentName.  
//    The Salaries table contains historical salary information for each employee, including their EmployeeID, Salary, and Date (when the salary was effective).  
//     Write an SQL query to find the top 3 departments with the highest average salary of employees hired in the year 2023.
