  9. U have an organizational structure, which shows hierarchy of the organization. This hierarchy contains employees
  10. E or managers M who has some Employees or Managers reporting to M.
  11. Employee has ( id, name, JobDesc, salary etc).
  12. Design the data structure you would be using to store this hierarchy
  13.  
  14. problem 1: Given an ID of an employee , print all the employee ID's who are directly reporting or indirectly
  15. reporting to the manager.
  16.  
  17. problem 2: prefix search of employees by String. If employees have nishant and nikhil. If searched by "ni" we need to print all details of both nishant and nikhil.
  18.  
  19. problem 3(bonus): search should print all emloyee's and their details if a given string is subString of the name of
  20.  an employee.(Like a phonebook contacts search)
