BBM 103: Introduction to Programming Laboratory I
Quiz 4
Subject: Collections & File I/O
Introduction
Within the context of this quiz, you are going to gain experience on using different
collections (dictionary, list and their functions) as well as on using File I \O. The scenario of
this work is receiving a message which is split into multiple packets and transferred over the
Internet. Packets are not received in order in which they are sent.
Your program must read the input file, sort the packets and write the completed messages
to an output file. You will not print output to terminal, you just have to write it into
output file which is given as system argument (outputFile.txt).
As you see from the input format, each line of input represents a single packet. each line is
formatted as given below:
X (tab) Y (tab) message part
X represents message ID, Y represents packet ID. It is guaranteed that there will be no
duplicate packets or message IDs.
