Question

This programming assignment requires you to implement two functions that are part of a server auditing application. Time is specified as an integer. Typically we specify time 0 to be a specific starting time eg.. "Jan 1, 2016 at 12 midnight" and count the number of seconds elapsed since that time. A server log is a list of N time intervals, wherein each interval (phi_i, u_i) specifics that some user was logged into the company server starting at time phi_i and ending at time u_i, with the starting/ending time points included. [(phi_1, u_1), (phi_2, u_2), (phi_3, u_3),...(phi_N, u_N)] You can assume that phi_i,

Explanation / Answer

Here is the code :

#!/usr/bin/python

# Function definition is here
def free_time_interval( array, endTime ):
   intervals = []
   # Creating a list and making all values to be 0.
   for index in range(0,endTime):
       intervals.append([])
       intervals.append(0);
   #based on start time and end time , initializing the previosuly created list with 1
   # so if an index contains 1 it means a user logged in at that time and if it is 0 then no one logged in
   for row in range(0,len(array)):
       startInt = array[row][0]
       if(array[row][1] >= endTime):
           endInt = endTime
       else:
           endInt = array[row][1]
       while(startInt <= endInt):
           intervals[startInt].append(1)
           startInt = startInt+1
   # Printing the values based on 1 and 0
   count = 0
   for rows in range(0,len(intervals)):
       if(intervals[rows][0] == 0):
           if(count%2 == 0):
               print(rows , " ")
           else:
               print(rows, ", ",rows+1)
               count = count+1

# Now you can call changeme function
array = []
array.append([])
array.append([])
array[0].append(1)
array[0].append(2)

array[1].append(3)
array[1].append(7)
free_time_interval( array, 5 )

Output would be:

0,1
