Print the names of the students who attended all of the week 4 Java events
Show the students who have attended most events. Show the students who have attended fewest events.
For each student for each subject (IIS, Java, PD, RAD) show the number of events attended for weeks 1 to 5 as a single digit:
Alpha A 32001 11001 21112 11000 Bravo B 21322 22121 32323 11000 Charlie C 21300 22100 31100 11000
In the example Alpha attended three IIS events in week 1, he attended 2 IIS events in week 2 but none in weeks 3 or 4. He attended one event in week 5. In Java he attended once in weeks 1,2 and 5 but none in 3 or 4.
Some events have attendance data recorded in some weeks but not others. Identify the events that took place in other weeks but did not have attendance data in week 4.
Identify the events that Alpha missed in week 3. Include only those that we can be certain were recorded.
The file tt.txt includes timetable data.
