Considering the following definition of class FACTORY, write a method in Python to search and display the content in a pickled file FACTORY.DAT,where FCTID is matching with the value '105'.

class Factory:
	def __init__(self,FID,FNAM):
		self.FCTID = FID # FCTID Factory ID
		self.FCTNM = FNAM # FCTNM Factory Name
		self.PROD = 1000 # PROD Production
	def Display(self):
		print self.FCTID,':',self.FCTNM,':',self.PROD

What will be the status of the following list after the First, Second and Third pass of the insertion sort method used for arranging the following elements in descending order?

22, 24, 64,
34, 80, 43
Note: Show the status of all the elements after each pass very clearly underlining the changes.

For a given list of values in descending order, write a method in python to search for a value with the help of Binary Search method. The method should return the position of the value and should return -1 if the value not present in the list.

Write Insert(Place) and Delete(Place) methods in python to add Place and RemovePlace considering them to act as Insert and Delete operations of the data structure Queue.
