Travelling PNR List - c++,Java,python spicycoders

A mini bus having S seats can be overbooked during festival times. Out of N bookings made C bookings can be cancelled. Hence the final travelling list has to be prepared for the first S bookings considering the cancellations. Each booking is assigned a PNR. Given the list of PNRs for all the bookings, the program must print the final list of PNRs for the confirmed bookings after cancellation. (The first S bookings remaining after cancellation are considered confirmed)

Input Format:
The first line contains S and N separated by a space.
Next N lines contain the PNRs of the N bookings made.
N+2 th line contains C
Next C lines contain the PNRs of the C bookings cancelled.

Output Format:
S lines contain the PNRs of the confirmed bookings.

Boundary Conditions:
5 <= S <= 30
2 <= N <= 50
N-C > 0
Length of PNR is from 1 to 20
