# It is decided that weekly greetings are to be furnished to wish the students having their 
# birthdays in that week. The consolidated sorted list with desired categorical information 
# is to be provided to the authority. Write a python program to store students PRNs with 
# date and month of birth. Let List_A and List_B be the two list for two SE Computer 
# divisions. Lists are sorted on date and month. Merge these two lists into third list 
# “List_SE_Comp_DOB” resulting in sorted information about Date of Birth of SE Computer 
# students
