# List manipulation

"""

The second year of engineering offers the following subjects in two departments. 

CSE = ["PQT", "ADC", "SE", "DPSD", "DS", "OOP"]

IT = ["OS", "PQT", "DS", "SE", "OOP", "SS"]

Write a program to create subject list for the two departments.  

Also find 

1. Number and names of subjects in CSE

2. Number and names of subjects in IT

3. Names of subjects in CSE only

4. Names of subjects in IT only

5. Number and names of subjects in both CSE and IT

6. Number and names of subjects for either CSE or IT, but not in both

7. Number and names of all subjects.
